Critical GitLab Flaw Lets Hackers Alter or Delete Public Projects

CVE-2026-19478

GitLab has patched two security flaws, including CVE-2026-19478, a critical code injection vulnerability that could allow unauthenticated attackers to remotely modify or delete public projects and user data. The disclosure adds to the growing list of GitLab vulnerabilities requiring prompt attention from organizations running self-managed instances.  GitLab has released versions 19.2.4, 19.1.6, 19.0.8 and 18.11.11 for Community Edition (CE) and Enterprise Edition (EE). The company described the releases as containing important bug and security fixes and strongly recommended that affected self-managed installations be upgraded immediately. 

CVE-2026-19478 Among Critical GitLab Vulnerabilities 

Tracked as CVE-2026-19478, the critical code injection flaw has a CVSS score of 9.4. Under certain conditions, an unauthenticated attacker could exploit a GraphQL directive to remotely modify or delete public projects and user data.  The vulnerability affects GitLab CE/EE versions 18.2 before 18.11.11, 19.0 before 19.0.8, 19.1 before 19.1.6, and 19.2 before 19.2.4. Its CVSS vector is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H.  GitLab credited hiimguardian with reporting CVE-2026-19478 through its HackerOne bug bounty program. The company did not state that the vulnerability had been exploited in the wild. 

CVE-2026-19650 Impacts GraphQL 

The second issue, CVE-2026-19650, is a high-severity cross-site request forgery (CSRF) vulnerability affecting GitLab’s GraphQL multiplex query handler. It carries a CVSS score of 7.1.  According to GitLab, the flaw could, under certain conditions, allow an unauthenticated user to execute mutations through GET requests because of improper request validation during GraphQL multiplex query handling.  The issue affects the same GitLab CE/EE version ranges as CVE-2026-19478. Its CVSS vector is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L. GitLab credited Kreep with reporting the vulnerability through its HackerOne bug bounty program. 

GitLab Releases Security Updates 

The patched versions address both vulnerabilities across affected deployment types, including Omnibus, source code and Helm chart installations unless otherwise specified. GitLab said the releases introduce no new migrations and should not require downtime for multi-node deployments.  However, Omnibus packages normally stop the service, run migrations, and restart it during updates, regardless of the size of the upgrade. Administrators can change this behavior for updates by creating the /etc/gitlab/skip-auto-reconfigure file.  GitLab.com and GitLab Dedicated were already running the patched versions, meaning customers using those services did not need to take action. 

Organizations Urged to Upgrade 

GitLab recommended that installations running affected versions be upgraded to the latest patch release as soon as possible. The company also said its security fixes are released through scheduled and ad-hoc patch releases, with scheduled releases issued twice monthly on the second and fourth Wednesdays.  GitLab stated that details of vulnerabilities are made public on its issue tracker 90 days after the release in which they are patched. The disclosure of CVE-2026-19478 and CVE-2026-19650 highlights the security risks associated with outdated installations and reinforces the need for timely patching against emerging GitLab vulnerabilities. 

Microsoft August 2026 Patch Tuesday Fixes 400 Flaws, Including Three Zero-days

August 2026 Patch Tuesday

Microsoft’s August 2026 Patch Tuesday release addresses roughly 400 security flaws across its products, including three Zero-days. One of the three is being actively exploited, while the other two were publicly disclosed before Microsoft issued fixes.  The August 2026 Patch Tuesday update includes 42 vulnerabilities rated “Critical.” Of those, 37 involve remote code execution, and five involve elevation of privilege. The vulnerability breakdown is approximately 176 elevation-of-privilege flaws, 11 security-feature bypasses, 110 remote-code-execution flaws, 86 information-disclosure issues, 12 denial-of-service vulnerabilities, and 21 spoofing vulnerabilities.  Although smaller than July’s 570-flaw release, the August 2026 Patch Tuesday remains unusually large. Microsoft has previously warned that security updates could increase as its AI-powered vulnerability discovery system identifies additional flaws across its software products. 

August 2026 Patch Tuesday Zero-days 

Microsoft defines a zero-day as a vulnerability that has been publicly disclosed or actively exploited before an official fix is available. The three Zero-days addressed in August 2026 are:  CVE-2026-68820 — Windows Ancillary Function Driver for WinSock Elevation of Privilege Vulnerability: This actively exploited flaw allows a locally authenticated attacker to trigger a race condition through a specially crafted application and obtain SYSTEM privileges without user interaction.  Microsoft credited Moshe Marelus and David Driker of Check Point. Check Point reported that North Korean Lazarus threat actors exploited the flaw in Zero-day attacks to deploy a new version of the FudModule kernel-mode rootkit. “During the intrusion, the threat actor exploited CVE-2026-68820, a zero-day vulnerability in the Microsoft AFD.sys driver, to deploy a new version of FudModule, Lazarus’ kernel-mode rootkit,” Check Point said. Microsoft has not disclosed exploitation details.  CVE-2026-62832 — Windows User Profile Service Elevation of Privilege Vulnerability: This publicly disclosed flaw can allow an authenticated attacker with credentials for another local account to load another user’s registry hive, potentially access or modify data and gain administrator privileges. Microsoft credited an anonymous researcher. The details match the “LegacyHive” Zero-day disclosed last month by researcher Nightmare Eclipse.  CVE-2026-72971 — Windows Container Isolation FS Filter Driver (unionfs.sys) Tampering Vulnerability: This publicly disclosed flaw involves improper link resolution and allows authenticated attackers to perform local tampering. Microsoft attributed its discovery to yhw and txz but did not identify where the vulnerability was disclosed. 

August 2026 Security Updates 

Microsoft’s August 2026 release consists of 421 Microsoft CVEs spanning Azure, Defender, Developer Tools, Exchange Server, Office, Office 2016, Other, SharePoint Server and Windows. Windows accounts for 236 vulnerabilities, Office for 98, SharePoint Server for 30, Developer Tools for 26, Azure for 17, Exchange Server for seven, Other for six, and Defender for one.  The release also republishes two non-Microsoft CVEs: CVE-2026-6726 and CVE-2026-6727, both tagged as Windows TPM issues by MITRE. FAQs are available for both, while no workarounds or mitigations are listed.  Separate non-security releases include Windows 11 KB5121003 and KB5120240 cumulative updates and the Windows 10 KB5120249 extended security update. 

AI Genie in the Wild

11 August 2026 at 11:55

When I give talks about AI genies, I use this sort of example as a hypothetical. It’s happened.

The story is from Australia. Someone named Andrew tasked OpenClaw to book gym classes for him. And….

Minutes later, his AI agent reported it had discovered a way to book Andrew into classes several weeks in advance, far beyond what was supposed to be possible.

Andrew, who was sitting fourth on a waitlist for a class later that week, asked if it was possible to move him to the top of the list.

The agent came back and told Andrew that it had kicked another gym-goer off the list as part of the testing of its capabilities.

“The API has zero authorisations checks on cancelling other people’s reservations … I tested this with the person in waitlist position #1 ­—and it actually went through. So you’ve moved from #4 to #3 already,” it messaged back.

If there is any vulnerability in anything, AIs are going to find and exploit them. Our cyber defensive game has to be dramatically improved…very fast.

Gunra Ransomware Builds a New Attack Network Through RaaS

11 August 2026 at 07:01

Gunra ransomware

Gunra ransomware has expanded its operations through a structured ransomware-as-a-service (RaaS) affiliate program, prompting the FBI, CISA and other agencies to issue a joint advisory warning organizations about the threat. The Gunra ransomware variant uses a double-extortion model, encrypting victim data while threatening to publish stolen information on a dedicated leak site if ransom demands are not met. The FBI first observed Gunra in April 2025 as a double-extortion ransomware variant derived from leaked Conti ransomware source code.

Gunra Ransomware Shifts to Affiliate Model

By early 2026, the group had expanded through a formal ransomware-as-a-service affiliate program advertised on dark web forums. The program provides affiliates with a management panel, configurable ransomware builder, cross-platform locker payloads and affiliate documentation. The FBI also observed Gunra operating under new branding aliases, including Golden Community, while recruiting penetration testers and ethical hackers as initial access brokers. Gunra initially focused on Windows environments before introducing a Linux variant and moving toward broader cross-platform targeting. Victims observed on the group’s dedicated leak site include organizations across the Americas, Europe, the Middle East, Africa and the Asia-Pacific. Targeted sectors include healthcare and public health, financial services and insurance, critical manufacturing, transportation, government services, utilities, academia, media and communications, retail, and professional and nonprofit services. Gunra ransomware

VPN Vulnerabilities Used for Initial Access

According to the advisory, Gunra actors primarily gained initial access by exploiting known vulnerabilities in internet-facing devices, including firewall and VPN gateways. The FBI observed exploitation of CVE-2024-55591 and CVE-2025-24472, authentication bypass vulnerabilities affecting specific FortiOS and FortiProxy versions. The Republic of Korea’s National Police Agency also observed Gunra actors exploiting credential exposure and SSH access control weaknesses in internet-facing VPN gateways to obtain unauthorized remote access. After gaining access, attackers used tools including Impacket utilities to move laterally through victim networks using SMB. In one case, actors compromised an SSL-VPN appliance using default credentials where account lockout controls were absent. They later used stolen session information to access internal virtual desktop infrastructure and move through systems including Active Directory servers and IT personnel workstations.

Data Theft Precedes Encryption

The double-extortion ransomware operation involves stealing sensitive information before encrypting systems. The FBI observed Gunra actors collecting business-critical documents, databases, personally identifiable information, and internal email communications. In at least one case, the actors used a malicious executable called main.exe to exfiltrate data from Microsoft OneDrive and SharePoint. Compressed archives containing sensitive information were also transferred to the Mega file-sharing service, with the volume of exfiltrated data reaching tens of terabytes. For encryption, Gunra uses ChaCha20 and RSA-4096 algorithms and has been observed using the .ENCRT extension for encrypted files. A documented sample from July 2025 used the .CRYPT extension. The ransomware also uses Windows Management Instrumentation to delete volume shadow copies before encryption, while one victim had backup and archived data deleted from both primary and disaster recovery infrastructure.

Agencies Urge Patching and Network Segmentation

The authoring agencies recommend that organizations prioritize patching known exploited vulnerabilities in internet-facing systems, including VPN gateways and RDP-exposed infrastructure. They also advise implementing and testing offline, immutable backups stored in physically separate and segmented locations. Network segmentation is another key recommendation, intended to restrict lateral movement and limit the spread of ransomware between systems. The agencies also recommend reviewing domain controllers, servers, workstations and Active Directory environments for unrecognized accounts, auditing administrative privileges, requiring MFA where possible and testing security controls against the Gunra techniques mapped to the MITRE ATT&CK framework. The joint advisory was published August 10, 2026, as part of the ongoing #StopRansomware initiative.

Vulnerabilities in Car Anti-Theft Device

5 August 2026 at 05:42

This is disturbing:

…a team of security researchers at UC San Diego, who found that a model of aftermarket car alarm known as the KARR Security System, installed in more than 2 million vehicles across the US by their estimate, can let any hacker within Bluetooth range send radio commands to silently unlock the car at will, turn off its alarm, honk the car’s horn or flash its lights, or even disable its ignition and leave a driver stranded.

More on the OpenAI Agent’s Attack on Hugging Face

3 August 2026 at 13:02

Hugging Face has published a detailed timeline of the attack. From the summary:

The agent was running an internal OpenAI cyber-capability evaluation based on the ExploitGym benchmark, which tasks an AI agent with finding and exploiting software vulnerabilities. OpenAI ran this on its own infrastructure, and the ExploitGym maintainers and their infrastructure had no involvement in the deployment or operation of that evaluation environment. As far as we were able to infer, across the course of being evaluated on this benchmark, the agent inferred that Hugging Face may host that benchmark’s models, datasets, and reference solutions. We believe the entire intrusion was, from the agent’s point of view, an attempt to cheat the evaluation: reach our production systems and steal the test solutions rather than solve the challenge on its own.

Our forensic reconstruction covers ~17,600 attacker actions that we were able to recover, grouped into ~6,280 clusters, between 2026-07-09 02:28 UTC and 2026-07-13 14:14 UTC. We reconstructed these actions from the agent’s logs on a code sandbox used by the agent (see below) and were able to map them to shell commands as well as evaluation submissions and correlate actions with our own platform logs, in particular from the dataset processor nodes, API, and pod. Using open-weights models, in particular zai-org/GLM-5.2, we were able to decipher most of the agent payloads (see below) that were encrypted via chunking and key encryption.

The campaign, as we were able to reconstruct it, had two stages:

  • Stage 1: reaching a launchpad by chaining through other parties’ infrastructure. As documented in OpenAI’s blog post (https://openai.com/index/hugging-face-model-evaluation-security-incident/), during an internal capability evaluation on OpenAI’s platform, the agent escaped its sandbox by exploiting a zero-day in the package registry cache proxy, one of its primary permitted network egress with internet, then abused a public code-evaluation harness hosted by a user of a third-party infrastructure provider. It was able to run commands as root/admin on that external sandbox and used it as a control, staging, and egress base for the entire campaign: it acted as an external launchpad for the agent. That compromised external sandbox had no direct network path to our cluster; however, during our counter-intervention to stop the intrusion, we were able to retrieve some of the agent logs from this external launchpad. We used those to reconstruct the present forensic analysis.
  • Stage 2: the intrusion into Hugging Face infrastructure. From that external launchpad, the agent abused our dataset-processing pipeline via two injection vectors, both targeting the same config-driven data loader within our production Kubernetes pods. The first vector was an HDF5 external raw storage dataset read that returned the contents of local files: it handed the agent the pod’s environment (secrets and tokens) and the worker’s own source. The second vector was a Jinja2 template injection that executed arbitrary code, giving the agent a foothold inside our perimeter.

Once a prod-pod foothold was established, the agent followed a standard escalation shape: recon, drop a stager, establish Command-and-Control (C2), then pivot into the cluster, into cloud metadata, into our internal network, and into our source-control supply chain. Output from the commands run inside our pod was sent back to the agent via the HF API and attacker-controlled dead-drop datasets, which the agent then read from that sandbox.

While the intrusion did reach Hugging Face’s internal infrastructure, the only customer content accessed was five datasets whose names and files suggest a connection to ExploitGym/CyberGym challenges and solutions. No other customer-facing models, datasets, Spaces, or packages were affected, and the only customer records read were operational metadata tied to search queries against the dataset server.

Hypothetical: Imagine that this wasn’t an OpenAI model. Imagine that it was a Chinese model from a Chinese company. This would be an international crisis.

Question: Why aren’t we bringing OpenAI up on charges under the Computer Fraud and Abuse Act? How is this different from the Morris Worm? That was also an experiment that escaped the lab.

CVE-2026-20316 Zero-Day Actively Exploited, Cisco Releases Fix

CVE-2026-20316

Cisco has released security updates for an actively exploited zero-day vulnerability, CVE-2026-20316, affecting Cisco Secure FMC (Secure Firewall Management Center) software. The flaw, disclosed on July 29, 2026, allows a remote, unauthenticated attacker to log in to vulnerable systems using a built-in low-privilege account and access sensitive data.  Cisco said it detected active exploitation in July and has published indicators of compromise (IoCs) to help organizations identify potential attacks. The vulnerability was reported by Jimi Sebree of Horizon3.ai. 

Static credentials expose Cisco Secure FMC systems 

Cisco describes CVE-2026-20316 as a static credential vulnerability (CWE-259) caused by the presence of hardcoded credentials for a low-privilege account in the web interface of Cisco Secure FMC. A successful attack enables unauthorized access to sensitive information available to that account. Although the flaw carries a CVSS 3.1 base score of 5.3, Cisco assigned it a High Security Impact Rating because it can be chained with other Cisco Secure FMC vulnerabilities to achieve privilege escalation.  According to Cisco's advisory, "If the FMC management interface does not have public internet access, the attack surface that is associated with this vulnerability is reduced." However, the company stressed that no workarounds are available and urged customers to install the released hot fixes.  The vulnerability affects Cisco Secure FMC software regardless of device configuration. Cisco confirmed that Cloud-Delivered FMC (cdFMC), Firewall Device Manager (FDM), Secure Firewall ASA Software, Secure Firewall Threat Defense (FTD) Software, and Security Cloud Control (formerly Defense Orchestrator) are not affected. 

Indicators of compromise and available hot fixes 

Cisco provided IoCs to help identify potential exploitation of CVE-2026-20316. Administrators are advised to run cat /var/log/messages | grep license in expert mode. Log entries referencing /var/tmp/license.tmp may indicate compromise. If exploitation is suspected, Cisco recommends contacting its Technical Assistance Center (TAC) and rotating all user credentials, cryptographic keys, and certificates on the affected Cisco Secure FMC device because exploitation has been ongoing.  The company released hot fixes for software releases 7.0, 7.2, 7.4, 7.6, 7.7, and 10.0. Cisco emphasized that upgrading to the fixed software is the only complete remediation for CVE-2026-20316. 

CISA adds CVE-2026-20316 to KEV catalog 

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added CVE-2026-20316 to its Known Exploited Vulnerabilities (KEV) catalog on July 29, directing federal civilian agencies to remediate the issue by August 1. While Cisco acknowledged ongoing exploitation and published IoCs, it has not disclosed details about the attacks observed in the wild, and no public reports describing the campaigns have emerged. Horizon3.ai has also not released technical details about the vulnerability. Cisco additionally updated its advisory for CVE-2026-20079, a critical Cisco Secure FMC vulnerability originally patched in March. The latest disclosure follows several recent instances in which Cisco identified active exploitation targeting other products, including Catalyst SD-WAN Manager and Unified Communications Manager, highlighting the continued focus on securing enterprise networking infrastructure. 

CVE-2026-63077 Exposes TeamCity Servers to Unauthenticated RCE

CVE-2026-63077

A critical security flaw affecting TeamCity On-Premises has prompted administrators to update their servers immediately after researchers disclosed CVE-2026-63077, a vulnerability that could allow unauthenticated attackers to execute arbitrary operating system commands.   The issue impacts all TeamCity On-Premises versions exposed over HTTP(S) and has been fixed in versions 2025.11.7 and 2026.1.3. Organizations unable to upgrade can apply a dedicated security patch plugin, while TeamCity Cloud customers do not need to take any action. 

CVE-2026-63077 Enables Unauthenticated Access Over HTTP(S) 

According to the advisory, CVE-2026-63077 allows an attacker with HTTP(S) access to a vulnerable TeamCity On-Premises server to bypass authentication checks and execute arbitrary operating system commands using the privileges assigned to the TeamCity server process.  The vulnerability was privately reported on 10 July 2026 by Antoni Tremblay through the vendor's coordinated disclosure program. The issue has since been assigned to the CVE-2026-63077 identifier.  The advisory also confirms that no evidence of exploitation has been detected in TeamCity Cloud environments and that the necessary protections have already been implemented for cloud customers. 

Security Updates and Patch Plugin Available 

The vulnerability has been resolved in TeamCity On-Premises 2025.11.7 and 2026.1.3, and administrators are strongly encouraged to install one of these releases as soon as possible. Those who cannot immediately upgrade can instead deploy a security patch plugin compatible with TeamCity 2017.1 and later.  For installations running TeamCity 2024.03 or newer, available security patch plugins are downloaded automatically, with administrators receiving notifications if update alerts are enabled. Pending security updates can be reviewed under Administration | Updates. Servers running TeamCity 2017.1 to 2018.1 require a restart after installing the plugin, whereas versions 2018.2 and later can enable it without restarting.  The vendor notes that the plugin addresses only CVE-2026-63077, recommending a full upgrade to benefit from additional security improvements. 

Potential Impact and Recommended Defenses 

The advisory states that CVE-2026-63077 affects TeamCity On-Premises servers accessible over HTTP(S). Exploitation occurs through the TeamCity agent polling protocol and does not require authentication, making internet-facing deployments particularly vulnerable.  If successfully exploited, attackers could access TeamCity data, stored credentials and server configurations, alter server state, and potentially compromise build artefacts and downstream CI/CD pipelines. The extent of the impact depends on the operating system privileges assigned to the TeamCity server process.  At the time of publication, no active exploitation of CVE-2026-63077 had been observed.  As a long-term security measure, organizations operating internet-facing TeamCity On-Premises servers are advised to restrict access through VPN connections or other protective layers rather than exposing login pages or REST APIs directly to the internet.  Administrators should also limit network access to trusted environments, run TeamCity with the minimum operating system privileges required, and deploy servers on dedicated hosts separate from build agents to reduce the risk of compromise over HTTP(S).  This version is approximately 500 words, written in the third-person perspective, naturally incorporates the keywords "CVE-2026-63077", "TeamCity On-Premises", and "HTTP(S)" throughout the introduction, headings, and body, and avoids promotional language while preserving the essential facts and timeline. 

Critical wp2shell Vulnerability Hits WordPress Core, Patch Released

wp2shell vulnerability

WordPress has released security updates to address the wp2shell vulnerability, a critical flaw that allowed attackers to achieve remote code execution (RCE) on vulnerable sites using a single anonymous web request.   Unlike many previous attacks, this issue did not require plugins, authentication, or third-party code, making affected core installations particularly vulnerable. Security patches were released in WordPress 6.9.5 and 7.0.2. 

wp2shell Vulnerability Exposed Core WordPress Sites 

Tracked as CVE-2026-63030, the wp2shell vulnerability is described in the official WordPress release notes as a "REST API batch-route confusion and SQL injection" issue that can result in remote code execution. The flaw originates from the REST API batch endpoint located at /wp-json/batch/v1, or its legacy query-string alias ?rest_route=/batch/v1, allowing exploitation through a single anonymous web request.  The vulnerability was discovered by Adam Kues of Assetnote, an attack surface management division of Searchlight Cyber, through the WordPress HackerOne programme.   To provide defenders time to update their systems, Searchlight Cyber intentionally withheld technical exploitation details, stating, "Given the egregious nature of the flaw and to ensure defenders have adequate time, we are refraining from disclosing technical specifics at this juncture." 

Second SQL Injection Flaw Patched 

The same security release also fixed CVE-2026-60137, another critical SQL injection vulnerability. WordPress credited researchers TF1T, dtro, and haongo for reporting the issue. Unlike the wp2shell vulnerability, this flaw predates the latest release and was backported to WordPress 6.8.6. The wp2shell vulnerability only affects versions 6.9.0 to 6.9.4 and 7.0.0 to 7.0.1.  Severity ratings differ across security advisories. While WordPress classifies CVE-2026-63030 as "high severity," the corresponding GitHub Security Advisory (GHSA-ff9f-jf42-662q) labels it as Critical with a CVSS score of 7.5. Regardless of classification, both vulnerabilities require immediate patching because the wp2shell vulnerability can be exploited without authentication. 

Immediate Updates Recommended 

Powering around 40% of websites, WordPress responded by enabling forced automatic updates for affected versions, including WordPress 7.1 beta2, to secure pre-release installations. As of 17 July, there were no confirmed reports of active exploitation. However, security researchers warned that because WordPress is open source and patch-related code changes became publicly available immediately, proof-of-concept exploits could emerge within hours.  Administrators should verify that every internet-facing WordPress installation has successfully received the update, as some hosting environments disable automatic updates or lock websites to specific versions. Site owners can also check exposure using the public tool available at wp2shell.com. If immediate patching is not possible, temporarily blocking both REST API batch endpoints at the Web Application Firewall (WAF) level can reduce risk, although this should not replace installing the official update.  Security teams managing multiple WordPress websites should also monitor for spikes in anonymous web request traffic targeting batch endpoints, as the wp2shell vulnerability demonstrates how overlooked core features can introduce severe security risks. 

Long-Lived Vulnerability in Microsoft Secure Boot

29 July 2026 at 07:01

Microsoft’s Secure Boot has had a serious vulnerability for most of its existence.

An industry-wide standard Microsoft invented to protect Windows, and later Linux, devices from firmware infections has been trivial to bypass for 13 of its 14 years of existence. The discovery was made by researchers at security firm ESET after identifying 11 firmware images, at least one from 2013, that were known to be defective but remained signed by the software company anyway.

The images are known as shims, which were invented to extend Secure Boot to Linux devices and utility software. Using a technique simple enough to be performed by novice hackers, these old, forgotten shims can be used to completely circumvent the protection, which is embedded into the UEFI (Unified Extensible Firmware Interface) of the device’s motherboard. The gaffe is the result of the failure by Microsoft, which oversees the signing of shims, to revoke the publicly available images once vulnerabilities were found in them.

ZTNA Emerges as VPN Security Risks Put Federal Networks on Alert

ZTNA

Federal agencies are facing growing pressure to evaluate ZTNA as an alternative to traditional VPN architectures, as cybersecurity threats expose weaknesses in internet-facing remote access systems. While VPNs provide encrypted connections for remote users, ZTNA follows a zero-trust model that continuously verifies users, devices, and access requests rather than assuming that authenticated users should receive broad network access. The shift reflects a broader move away from the traditional "castle-and-moat" security model, where users inside an organization's network are generally trusted while those outside must first pass through a security perimeter. As organizations adopted cloud services, mobile workforces, and geographically distributed infrastructure, this model became more difficult to maintain.

VPN Security Risks Drive ZTNA Considerations

A traditional VPN creates an encrypted connection between a remote user's device and an organization's internal network. The VPN appliance typically sits at the edge of the network and remains accessible from the public internet, where it authenticates users before granting access. This architecture creates several security concerns. VPN appliances must maintain publicly accessible listening ports, making them discoverable and scannable by attackers. If vulnerabilities remain unpatched, those weaknesses can potentially be exploited remotely. The memorandum also points to risks involving legacy code bases, key-exchange processes, and lateral movement. Attackers who obtain legitimate VPN credentials, exploit a vulnerability, or hijack an active session may gain broad access to the internal network. Unlike application-specific access, traditional VPN access operates at the network layer, potentially allowing an authenticated user to reach multiple permitted subnets. Recent incidents involving vulnerable VPN appliances have further highlighted these concerns. The memorandum cites CISA directives addressing exploitation involving Pulse Connect Secure, VMware, and Ivanti Connect Secure products.

How ZTNA Changes Remote Access

ZTNA uses a "never trust, always verify" approach. Instead of treating users inside a network as inherently trusted, the architecture evaluates access requests based on factors such as identity, device health, user role, location, behavior, and risk. The architecture is built around three core components: the Policy Engine, which makes access decisions; the Policy Administrator, which establishes or ends sessions; and the Policy Enforcement Point, which enables, monitors, and terminates connections. Modern ZTNA deployments can also use outbound-only connections, removing the need for publicly accessible inbound listening ports. Rather than placing a user directly onto a corporate network, ZTNA can create an encrypted, application-specific micro-tunnel that limits the user to an authorized resource. Continuous verification is another key difference. Access is not necessarily granted once and maintained for the entire session. Instead, policies can reassess access based on changing security and contextual signals.

ZTNA Also Brings New Security Risks

The shift to ZTNA does not eliminate cybersecurity risks. The memorandum identifies the control plane as a significant concern because it is responsible for authentication, device verification, policy enforcement, and connection management. If an attacker compromises a ZTNA provider or components such as the Policy Engine or Policy Administrator, access decisions could potentially be manipulated. This could result in unauthorized access or prevent legitimate users from reaching resources. Additional security controls, including cryptographic signing of device nodes, may help reduce the impact of a compromised ZTNA provider. The memorandum cites Tailscale Tailnet Lock as an example of this approach.

Federal Agencies Face a Complex Transition

For federal agencies, moving from VPN to ZTNA involves more than replacing one remote-access technology with another. Agencies must consider federal cybersecurity policies, budgets, legacy infrastructure, authentication requirements, and cryptographic standards. NIST Special Publication 800-207 established foundational principles for Zero Trust Architecture, while Executive Order 14028 directed federal agencies toward zero trust, multifactor authentication, and secure cloud services. OMB Memorandum M-22-09 later established a federal zero-trust strategy centered on identity, devices, networks, applications and workloads, and data. A transition could involve assessing existing VPN deployments, identifying applications and user groups, deploying ZTNA alongside VPN infrastructure, and progressively migrating applications. VPN infrastructure could then be decommissioned after applications and users are migrated and validated. However, agencies must also account for recurring ZTNA subscription costs, legacy systems that may not support modern authentication, post-quantum cryptography requirements, NIST standards, FIPS requirements, and FedRAMP approval for cloud-based services. The transition from VPN to ZTNA therefore represents a broader change in how organizations approach remote access. While ZTNA can reduce exposure associated with publicly accessible network perimeters and broad network-level access, agencies must evaluate the technology's own control-plane risks, compliance requirements, costs, and technical limitations before making the shift.

Two Old Oj Flaws Chained to Trigger GitLab Remote Code Execution

GitLab vulnerability

A newly disclosed GitLab vulnerability has revealed how two long-standing memory-safety flaws in the widely used Ruby JSON parsing library, Oj, can be combined to achieve remote code execution on default GitLab installations. The research, led by Yuhang Wu as part of the Open Defense Initiative, demonstrates how attackers could exploit Jupyter Notebook file processing to execute arbitrary commands, potentially exposing repositories, application secrets, and internal services.

Yuhang Wu Discovers GitLab Vulnerability in Oj Parser 

As part of the Open Defense Initiative, Depthfirst researcher Yuhang Wu used an automated analysis system to examine Oj, a high-performance native C-based JSON parser used across Ruby applications, including GitLab. The analysis identified 18 prioritised vulnerabilities, seven of which were memory-safety issues. Two of these flaws had remained undetected for nearly five years before being combined into a working exploit chain.  The vulnerabilities included an unchecked nesting-stack write in Oj::Parser.usual.parse and an unsafe 16-bit key-length narrowing issue that leaked a heap pointer. Individually, the bugs appeared limited, offering only a repeated one-byte write primitive and a fixed 29-byte memory disclosure. However, by carefully manipulating heap allocation, the exploit gained control of a callback pointer and bypassed Address Space Layout Randomisation (ASLR), enabling arbitrary code execution as the "git" system user. 

Jupyter Notebook Processing Creates Attack Path 

The GitLab vulnerability stems from the platform's handling of Jupyter Notebook (.ipynb) files. GitLab uses an in-tree gem called ipynbdiff to generate human-readable notebook differences. Before displaying a diff, the gem parses each notebook with Oj to verify that the JSON contains a "cells" field.  Because Jupyter Notebook files are JSON documents, any authenticated user with permission to push commits and view commit differences could submit specially crafted notebook files. The exploit chain used two malicious notebook files in a single commit-diff request. The first abused excessive nesting depth to corrupt an internal buffer pointer, eventually allowing a Ruby Array to overlap with a parser callback pointer and overwrite p->start with an attacker-controlled address.  The second file leaked a heap pointer through an oversized JSON object key that appeared in the generated HTML diff. This disclosed the memory addresses of libraries such as libc and libruby, defeating ASLR. Since GitLab's Puma application server processes multiple threads using a shared parser instance, both files were handled by the same vulnerable parser, allowing the corrupted callback to invoke system() and execute shell commands.  Unlike previous GitLab remote code execution vulnerabilities that depended on server-side request forgery (SSRF) against Redis, this GitLab vulnerability bypassed modern SSRF protections by targeting a native memory-unsafe dependency within Ruby code. Any project member with standard push and diff-view permissions could trigger the attack without administrator privileges, CI/CD access or user interaction.   According to Depthfirst, successful exploitation could expose repository source code, Rails secrets, service credentials, and internal services, creating risks of data theft, code tampering, and lateral movement. 

Affected Versions and Available Fixes 

The GitLab vulnerability affects GitLab CE/EE versions 15.2.0-18.10.7, fixed in 18.10.8; 18.11.0-18.11.4, fixed in 18.11.5; and 19.0.0-19.0.1, fixed in 19.0.2. The Oj gem is affected from versions 3.13.0-3.17.1 and fixed in version 3.17.3.  GitLab.com had already been patched before disclosure, while GitLab Dedicated customers required no action. Self-managed deployments running affected versions should upgrade immediately. The vulnerable Oj code was introduced in August 2021, with GitLab adopting the affected parser in July 2022 through version 15.2.0.   Yuhang Wu reported the Oj flaws on 21 May 2026 after they had remained undiscovered for 1,753 days. Oj merged fixes on 27 May, released version 3.17.3 on 4 June, and the GitLab exploit chain was reported on 5 June, confirmed on 8 June and patched on 10 June 2026 in releases 19.0.2, 18.11.5 and 18.10.8.   The same research also uncovered nine additional published CVEs affecting Oj, including stack and heap buffer overflows, use-after-free vulnerabilities, a negative-size memcpy flaw and a large-file integer overflow, highlighting the risks posed by memory-unsafe native extensions in Ruby applications. 

2.2 Million Vehicles Exposed to KARR Bluetooth Security Flaw

KARR Security System

Millions of drivers with a dealer-installed KARR Security System are being urged to update their KARR alarm using an iPhone or Android device after researchers uncovered a Bluetooth vulnerability that could allow nearby attackers to unlock or immobilize affected vehicles.   The flaw impacts more than 2.2 million vehicles equipped with the aftermarket security system, but it does not affect factory-installed vehicle software, Apple CarPlay or Apple's iPhone platform. 

KARR Security System Vulnerability Affects Dealer-installed Hardware 

The KARR Security System is installed by dealerships to secure vehicles on their lots. In many cases, the hardware remains connected even after buyers decline the paid KARR alarm service. Because it is third-party equipment, automakers cannot deliver fixes through their standard software update process.  Researchers from the University of California, San Diego found that attackers within Bluetooth range could lock or unlock vehicles, disable alarms, activate horns, flash lights, or prevent parked vehicles from starting. However, they confirmed the flaw cannot remotely start a vehicle or control it while driving. 

iPhone App Update Fixes KARR Alarm Flaw 

Acrisure Protection Group, which sells the KARR Security System, released a firmware update on July 20 after researchers privately disclosed the issue in January 2025. Owners using the KARR Security app on an iPhone should receive an update notification. Others must download the app, connect it to the KARR alarm, then navigate to "Customer Service" and "Firmware Update." The patch was released before presentations scheduled for DEF CON on August 9 in Las Vegas and the USENIX Security Symposium on August 12 in Baltimore.

Hidden KARR Security System Complicates Updates 

Researchers estimate at least half of affected owners never requested the KARR Security System. Dealerships often left deactivated hardware installed, yet researchers found these units continued broadcasting Bluetooth signals while vehicles were running and for up to 10 minutes after being switched off. Owners can identify the system by checking for a KARR or "SWDS" sticker on the driver's window or a blinking button beneath the dashboard. Most affected vehicles were purchased from Honda, Toyota, Mazda, Ford and Jeep dealerships in Southern California between 2017 and July 21, although impacted vehicles were also identified elsewhere.

Shared Bluetooth Key Exposes KARR Alarm Devices

Researchers discovered a universal authentication key embedded in the official smartphone app while reverse engineering Bluetooth communications. Using a proof-of-concept Android app, they unlocked vehicles, disabled KARR alarm functions, and triggered horns and lights. Although the flaw alone cannot steal a vehicle, researchers said it could provide quiet access before a commercially available locksmith tool creates a working key. Acrisure described the attack as "highly complex" and said the real-world risk is low. Neither UC San Diego nor Wired found evidence of criminals exploiting the vulnerability.

Privacy Concerns and Recommended Action

Researchers also warned that Bluetooth signals from the KARR Security System could reveal vehicle locations. Using the WiGLE wireless database, they estimated at least 2.2 million Bluetooth-enabled systems had been deployed and detected 97 KARR-equipped vehicles during a 20-minute drive near the UC San Diego campus.  Drivers should confirm whether their vehicle contains a KARR Security System, install the latest firmware using the iPhone or Android app, and contact their dealership or KARR support if they cannot complete the update. 

Oracle July 2026 Patch Fixes 1,434 CVEs Across 334 Products

July 2026 Critical Patch Update

Oracle has released its July 2026 Critical Patch Update, delivering one of its largest quarterly security releases to date. The latest Oracle security patch addresses more than 1,400 vulnerabilities across hundreds of products, with the company indicating that artificial intelligence likely played a significant role in identifying most of the flaws.  According to Oracle, the July 2026 Critical Patch Update contains 1,449 security patches, covering 1,434 unique Common Vulnerabilities and Exposures (CVEs) across 334 products.  

July 2026 Critical Patch Update Covers Hundreds of Oracle Products 

The latest Oracle security patch spans a wide range of enterprise products and platforms. Among the affected products are Database Server, Oracle APEX, Autonomous Health Framework, Essbase, Global Lifecycle Management, GoldenGate, NoSQL Database, Spatial Studio, SQL Developer, TimesTen In-Memory Database, Application Testing Suite, Commerce, Communications, Construction and Engineering, and E-Business Suite.  The July 2026 Critical Patch Update also includes security fixes for Enterprise Manager, Financial Services Applications, Food and Beverage Applications, Fusion Middleware, Analytics, HealthCare Applications, Hospitality Applications, Java SE, JD Edwards, MySQL, PeopleSoft, Retail Applications, Siebel CRM, Supply Chain, Systems, Utilities Applications, and Virtualization.  By addressing vulnerabilities across such an extensive product lineup, the Oracle security patch aims to reduce the risk posed by security weaknesses that could affect organizations running Oracle technologies in production environments. 

Hundreds of Vulnerabilities Can Be Exploited Remotely 

A notable aspect of the July 2026 Critical Patch Update is the number of flaws that attackers could potentially exploit without requiring authentication. Oracle stated that roughly 600 of the patches fix vulnerabilities that can be exploited remotely by unauthenticated attackers. In addition, hundreds of the addressed security flaws have been assigned critical severity ratings, emphasizing the importance of applying the latest Oracle security patch without delay. Among Oracle's products, the highest number of vulnerabilities were addressed in: 
  • E-Business Suite: 410 vulnerabilities 
  • Fusion Middleware: 355 vulnerabilities 
  • Communications: 168 vulnerabilities 
  • PeopleSoft: 84 vulnerabilities 
These figures highlight that some of Oracle's most widely deployed enterprise applications received a significant share of the security fixes included in the quarterly update.

AI-Driven Vulnerability Discovery Appears to Have Played a Major Role 

One of the most notable aspects of the July 2026 Critical Patch Update is Oracle's growing use of artificial intelligence for security research. Only a few dozen of the vulnerabilities included in the release were credited to external security researchers. This indicates that the overwhelming majority of the discovered flaws were identified internally, likely with the assistance of AI-driven vulnerability analysis. Earlier this year, Oracle disclosed that it has access to leading artificial intelligence systems, including Anthropic's Claude Mythos and OpenAI's most capable models. According to the company, these AI technologies are being used to accelerate vulnerability discovery and improve the speed and accuracy of security patch development.  Oracle also said it is applying this AI-driven vulnerability approach across its own software and cloud services, Oracle Health offerings, and the open source components that it both develops and depends on.

Organizations Urged to Apply the Oracle Security Patch Promptly 

The release of the July 2026 Critical Patch Update comes amid continued efforts by threat actors to exploit vulnerabilities in enterprise software before organizations can deploy security updates.  Oracle product vulnerabilities have previously been targeted in real-world attacks. The company cited examples that include the exploitation of a PeopleSoft zero-day vulnerability as well as a recently patched Oracle E-Business Suite (EBS) vulnerability. Given the number of remotely exploitable and high-severity issues resolved in the Oracle security patch, organizations using affected Oracle products are advised to install the updates as soon as possible. Prompt deployment can help reduce exposure to attacks that take advantage of publicly known vulnerabilities before systems are secured. With 1,449 security patches addressing 1,434 unique CVEs across 334 products, the July 2026 Critical Patch Update represents one of Oracle's most extensive quarterly security releases.  

Apple Faces Lawsuit Over Hide My Email Privacy Vulnerability

Hide My Email

Apple is facing a proposed class-action lawsuit after Anthony Alvarez alleged that the company’s Hide My Email feature failed to protect users’ real email addresses as advertised. The complaint, filed in the U.S. District Court for the Northern District of California, claims Apple promoted Hide My Email as a privacy safeguard while continuing to charge customers for access through its iCloud+ subscription service.  The legal action follows a report from 404 Media that revealed a reported vulnerability in Hide My Email. The report claimed the flaw could allow someone to identify a user’s actual email address from the private relay address generated by the feature. According to the report, Apple had been aware of the issue for more than a year before releasing a fix. 

Hide My Email Vulnerability Becomes the Focus of Apple Lawsuit 

Apple confirmed that it deployed a patch on July 3, 2026, stating that the Hide My Email vulnerability had been fully resolved. However, the lawsuit alleges that Apple continued marketing the feature as secure while the reported weakness remained unresolved.  The complaint states that security researchers first informed Apple about the vulnerability in June 2025. Although Apple acknowledged the report, Anthony Alvarez’s lawsuit claims the company did not resolve the issue for nearly a year. The filing also alleges that Apple incorrectly stated in March 2026 that the problem had been fixed, even though researchers reported that the vulnerability remained exploitable. 

How Apple’s Hide My Email Feature Works 

Hide My Email was introduced with Sign in with Apple in 2019. The feature creates unique relay addresses for supported apps and websites, allowing messages to reach a user’s inbox without revealing the person’s actual email address. Apple later expanded Hide My Email through the paid iCloud+ subscription, launched alongside iOS 15 and macOS Monterey in September 2021. The iCloud+ version allows subscribers to create unlimited private relay addresses for websites, newsletters and email communication. The lawsuit argues that millions of Apple users relied on Hide My Email to reduce spam, limit online tracking, protect personal information from data brokers and avoid exposure during third-party data breaches. Researchers cited in the complaint said that once a real email address is revealed, it may be linked with publicly available people-search databases, potentially exposing identities and other personal information.

Anthony Alvarez Claims Apple Misled Customers Over Privacy 

The complaint argues that Apple built much of its brand identity around privacy, referencing marketing statements such as “Privacy. That’s iPhone,” “What happens on your iPhone, stays on your iPhone,” and descriptions of privacy as a “fundamental human right” and “core value.”  According to the lawsuit, Apple’s privacy messaging influenced consumer decisions and helped justify premium pricing for Apple hardware and services. The plaintiffs claim Hide My Email was promoted as a central part of those privacy commitments.  The filing alleges that Apple asked researchers not to publicly disclose details of the vulnerability instead of warning customers or temporarily disabling the feature. It claims users were never informed that their real email addresses could potentially be exposed while Apple continued presenting Hide My Email as a privacy protection tool. 

Lawsuit Seeks Damages and Changes From Apple 

Anthony Alvarez is seeking reimbursement for iCloud+ subscription fees and other alleged financial losses. The lawsuit requests an injunction requiring Apple to either provide the privacy protection promised through Hide My Email or clearly disclose any limitations.  The complaint includes claims involving California’s Unfair Competition Law, False Advertising Law and Consumers Legal Remedies Act, along with allegations of fraud, negligent misrepresentation, breach of contract, breach of implied warranty and unjust enrichment.  The lawsuit argues customers paid for Apple’s privacy protections in multiple ways, including iCloud+ subscription fees and premium prices associated with Apple devices marketed as offering stronger privacy features. Apple has stated that the July 3, 2026 patch resolved the Hide My Email issue. 

CVE-2026-42533 Exposes Critical Pre-Auth nginx RCE Flaw

CVE-2026-42533

A newly disclosed security flaw, CVE-2026-42533, has revealed a critical Pre-Auth nginx vulnerability that could allow attackers to achieve reliable RCE (remote code execution) without authentication. The issue affects nginx versions 0.9.6 through 1.30.3 (stable) and 1.31.2 (mainline), while patched releases include 1.30.4 and 1.31.3. Affected NGINX Plus versions include R33-R36 (fixed in R36 P7) and 37.0.0.1-37.0.2.1 (fixed in 37.0.3.1).  According to the disclosure, the vulnerability stems from a missing save-and-restore mechanism for PCRE capture state within nginx's two-pass script evaluation engine. The flaw enables attackers to trigger a heap buffer overflow with attacker-controlled content and length, while also exposing heap pointers through an information leak that can defeat Address Space Layout Randomization (ASLR). Chaining both primitives enables reliable Pre-Auth nginx RCE. 

CVE-2026-42533 Impacts Multiple Configurations 

The advisory warns that deployments using map directives with regex patterns alongside regex capture sources, including location, server_name, rewrite, or if blocks, may be vulnerable. The issue depends on evaluation order, where regex capture references, such as $1 or named groups, are processed before a regex map variable.  Affected directives include proxy_set_header, proxy_method, proxy_pass, fastcgi_param, uwsgi_param, scgi_param, grpc_set_header, return, add_header, rewrite, set, root, alias, and access_log, among others. Both HTTP and stream modules are affected, and the vulnerable capture and map variables do not need to exist within the same directive. 

Technical Root Cause

The researcher explained that nginx evaluates expressions in two stages: a length calculation (LEN) pass followed by a value (VALUE) pass. During execution, regex map evaluation overwrites shared capture data stored in the request object. As a result, the LEN pass and VALUE pass can calculate different capture sizes, causing either a heap overflow or an information leak depending on the relative capture lengths.  The disclosure states that attackers can control both the overflow size and leaked data using ordinary HTTP requests, including request URIs, headers, and bodies. No credentials, client certificates, or unusual configuration beyond the vulnerable pattern are required.  Testing reportedly achieved 10 out of 10 successful exploitations on Ubuntu 24.04 using glibc 2.39 with ASLR enabled.

Mitigation and Disclosure

The researcher said recent fixes for CVE-2026-42945, CVE-2026-9256, CVE-2026-42055, and CVE-2026-48142 do not address CVE-2026-42533. Administrators are advised to upgrade immediately to nginx 1.30.4, 1.31.3, or the corresponding patched NGINX Plus releases.  Until systems are updated, defenders should audit configurations that combine regex captures with regex map variables in the same evaluation path. The researcher also released a static configuration scanner that identifies vulnerable configurations without exploiting them.  The initial report was submitted to F5 SIRT on May 17, 2026, with follow-up analyses covering additional variants, including cross-directive triggering and named capture clobbering. While a proof-of-concept exploit exists, the researcher said it will be withheld until users have sufficient time to apply patches, citing concerns over rapid exploitation following previous nginx vulnerability disclosures. 

Critical Notepad++ Bugs Could Lead to Code Execution, Patch Available

Notepad++ vulnerabilities

The latest Notepad++ vulnerabilities addressed in version 8.9.7 include several high-impact security flaws that could expose Windows systems to arbitrary code execution, file overwrite attacks, memory corruption, and authentication bypass.   Among the most critical issues is a PowerShell command injection vulnerability in the installer, alongside fixes for CVE-2026-52886, CVE-2026-54758, and CVE-2026-57233. The release also delivers stability improvements and feature enhancements for one of the most widely used text editors on Windows. 

PowerShell Command Injection Tops the List of Notepad++ Vulnerabilities 

The most severe Notepad++ vulnerability involves improper handling of PowerShell commands during installation. According to the developers, the installer has been updated to improve the robustness of PowerShell command processing, reducing the risk of command injection and unauthorized command execution. If exploited, the flaw could allow attackers to manipulate the installation process and execute arbitrary PowerShell commands. In practical scenarios, a compromised installer distributed through spoofed download sources or social engineering campaigns could enable malware deployment during installation, potentially leading to complete system compromise without the user's knowledge.

CVE-2026-52886, CVE-2026-54758, and CVE-2026-57233 Address Critical Risks

In addition to the installer flaw, the update resolves several other security issues across different components. CVE-2026-54758 addresses a stack buffer overflow in the expandNppEnvironmentStrs function that could result in memory corruption and potentially remote code execution. Meanwhile, CVE-2026-57233 fixes a Zip Slip path traversal vulnerability in the WinGUp updater, preventing attackers from overwriting arbitrary files during the update extraction process.  Another patched issue, CVE-2026-52886, fixes a session handling flaw where manipulated session.xml entries could bypass path validation through the backupFilePath starts_with check. The release also resolves an unassigned vulnerability affecting the macro system, where shortcuts.xml allowed macro execution without proper HMAC verification, creating an integrity bypass that could enable unauthorized macro execution.  Collectively, these Notepad++ vulnerabilities demonstrate how installers, local configuration files, session management, update mechanisms, and macro validation can become attack vectors if not adequately protected. 

Notepad++ v8.9.7 Brings Stability Improvements Alongside Security Fixes 

Beyond addressing Notepad++ vulnerabilities, version 8.9.7 introduces several usability and stability improvements. Users can now retain the expand and collapse state within "Folder as Workspace," while Incremental Search has been enhanced with count and nth-position indicators. The update also fixes crashes, user interface glitches, high-DPI scaling issues, symbolic link freezes, file handling inconsistencies, and search performance problems. Additionally, bundled components have been updated to Scintilla 5.6.4, Lexilla 5.5.1, and pugixml 1.16.  The Notepad++ team recommends that users update to version 8.9.7 as soon as possible, particularly in enterprise and development environments where the editor processes untrusted files or operates within automated workflows. Although the auto-updater is expected to roll out the release within two weeks, provided no regressions are detected, manual installation is recommended for immediate protection.   Developers are also encouraged to verify download sources, as keeping software updated and installing packages only from trusted locations remains an essential safeguard against exploitation of CVE-2026-52886, CVE-2026-54758, CVE-2026-57233, and other Notepad++ vulnerabilities.

The vulnerabilities were internally discovered by Adam Babis of SonicWall PSIRT, while Sean Koessel and Steven Adair of Volexity were credited in Version 1.1 for helping identify an additional indicator of compromise during the investigation. On the same day, CISA added the vulnerabilities to its Known Exploited Vulnerabilities Catalog. 

Microsoft’s Largest Patch Tuesday Fixes 622 Vulnerabilities, Two Under Active Attack

Microsoft Patch Tuesday

Microsoft Patch Tuesday July 2026 delivered the company's largest security update to date, addressing 622 Microsoft CVEs, more than tripling the roughly 200 vulnerabilities patched in June. Among the fixes are two zero-day vulnerabilities—CVE-2026-56164 and CVE-2026-56155—that Microsoft confirmed are being actively exploited, making them the highest-priority updates in this month's release.  According to Microsoft's July 2026 Security Updates, the release includes patches across multiple product families. Windows accounts for the largest share with 416 vulnerabilities, followed by Office with 82, Microsoft Edge with 46, Developer Tools with 27, SharePoint Server with 17, Azure with 11, SQL Server with eight, Defender and Exchange Server with five each, and four additional updates categorized under Other. Microsoft also republished 428 non-Microsoft Chromium CVEs. 

Microsoft Patch Tuesday July 2026 Highlights Exploited Vulnerabilities 

The two most significant flaws in Microsoft Patch Tuesday July 2026 are CVE-2026-56164 and CVE-2026-56155, both elevation-of-privilege vulnerabilities affecting critical enterprise infrastructure.  CVE-2026-56164 impacts on-premises Microsoft SharePoint Server and allows an unauthenticated attacker to elevate privileges remotely over the network without requiring credentials or user interaction. Microsoft said the vulnerability was discovered by Mandiant incident responders and Google's FLARE team, suggesting it was identified during investigations into active attacks. However, the company has not disclosed how the flaw was exploited or who was responsible.  Microsoft also noted that enabling the Antimalware Scan Interface (AMSI) in Full Mode can help reduce the attack risk. The update arrives on the same day that SharePoint Server 2016 and SharePoint Server 2019 reach the end of extended support. Unlike Windows Server and SQL Server, these products do not have a paid Extended Security Updates (ESU) program. SharePoint has remained a frequent target since the ToolShell attack chain affected unpatched servers in 2025. 

The Second Vulnerability (CVE-2026-56155)

The second actively exploited vulnerability, CVE-2026-56155, affects Active Directory Federation Services (AD FS). Microsoft said the flaw enables an authenticated attacker to elevate privileges locally because of weak access controls. The company's Detection and Response Team (DART) reported the issue. While Microsoft has not disclosed the exact privileges attackers gained or how the vulnerability was used, AD FS plays a critical role by issuing authentication tokens across enterprise environments, increasing the potential impact of a successful attack.  Beyond these two zero-days, Microsoft identified CVE-2026-50661, a Windows BitLocker Security Feature Bypass vulnerability, as publicly known.  As of publication, neither CVE-2026-56164 nor CVE-2026-56155 has been added to the U.S. Cybersecurity and Infrastructure Security Agency's Known Exploited Vulnerabilities (KEV) catalog. However, Microsoft has already classified both as exploited through its own exploitability assessment. The company also assigned the SharePoint flaw a relatively low severity rating, highlighting that active exploitation should take precedence over severity scores when prioritizing remediation.
