GitLab’s critical flaw is already drawing internet-wide probes

GitLab patches two critical flaws (CVE-2026-85706 CVSS 10.0, CVE-2026-87719) as WatchTowr observes internet-wide probing of the unauthenticated file-read bug.

GitLab released emergency patches for two high-severity flaws in Community and Enterprise Editions, urging self-managed operators to upgrade immediately while saying its hosted and Dedicated offerings are fixed or unaffected. CVE-2026-85706 (CVSS 10.0) is a path traversal in the repository commits interface that lets unauthenticated attackers read any file on the server and affects releases 18.7 through 19.1.8 plus the 19.2 and 19.3 lines before patching. CVE-2026-87719 (CVSS 9.9, Enterprise Edition only) lets a logged-in Duo Chat user hide a command in a request that triggers Advanced Search settings and password disclosure. WatchTowr Labs reported it is already watching probes that can trigger the path traversal flaw in a single HTTP request, though CISA had not added either issue to the KEV list as of Friday afternoon.

  • Unauthenticated Path Traversal Arbitrary File Read in GitLab CE/EE
    CVE-2026-85706 is a path traversal flaw (CWE-35) in GitLab Community Edition and Enterprise Edition in which the repository commits API does not properly confine file paths and does not enforce authentication, allowing an unauthenticated attacker to read arbitrary files from the GitLab server. It is triggered by sending a crafted unauthenticated request to the commits API that supplies traversal sequences moving outside the intended repository path. An attacker gains the ability to read arbitrary files on the host, which can expose configuration files, certificates, and stored credentials or keys; related reporting on the recent GitLab patch wave also notes credential theft and code execution flaws, though this CVE itself is the file-read issue. All self-managed GitLab CE and EE deployments are in scope, and CISA did not publish specific affected version ranges in this data. The flaw was added to CISA's KEV catalog on 2026-09-11 and is being actively probed and exploited in the wild within a day of disclosure, with three public proof-of-concept repositories available; ransomware use is not yet confirmed.

  • Memory Buffer Overflow in Citrix NetScaler ADC/Gateway Exploited in the Wild
    CVE-2026-8452 is a memory buffer overflow (CWE-119) in Citrix NetScaler ADC and NetScaler Gateway that applies when the appliance is configured as a Gateway (SSL VPN, ICA Proxy, CVPN, or RDP Proxy) or as an AAA virtual server. The flaw is reachable over the network without authentication (CVSS 4.0: AV:N/PR:N), so an unauthenticated attacker can trigger it remotely. Successful exploitation causes unpredictable or erroneous appliance behavior and denial of service, and the high confidentiality score suggests possible disclosure of memory contents; some reporting suggests pre-authentication remote code execution may be possible, though the vendor description emphasizes DoS. Organizations running affected NetScaler appliances in a Gateway or AAA role — a very common configuration for remote access to Citrix virtual apps and desktops — are potentially exposed. The flaw was added to CISA's KEV catalog on 2026-08-26 and is reported as exploited in the wild, with headlines noting the flaw was already patched before exploitation was confirmed.

  • Authenticated GraphQL Subscription Flaw Leaks Search Credentials in GitLab EE
    GitLab EE contains a critical (CVSS 9.9) deserialization flaw (CWE-502) in which an authenticated user with Duo Chat access can pass a specially crafted GraphQL subscription argument that bypasses serialization and performs a server object lookup. Via this bypass, the attacker can obtain Advanced Search instance configurations and the sensitive credentials they contain. Because the attack requires only a low-privileged account with Duo Chat access over the network, with no user interaction, any EE deployment where Duo Chat is enabled is potentially exposed, including both self-managed instances and GitLab.com. Affected versions are EE 18.3 and later before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2. No public proof-of-concept or CISA KEV listing exists for this CVE as of now, though related GitLab flaws disclosed in the same cycle are reportedly drawing internet-wide probing.
