Critical GitLab Flaws Let Attackers Read Arbitrary Files, Steal Credentials and Execute Code
GitLab issues emergency patches for critical path-traversal flaw CVE-2026-85706 (CVSS 10.0), GraphQL credential exposure CVE-2026-87719, and potential RCE flaw CVE-2026-88765.
GitLab released versions 19.3.2, 19.2.6, and 19.1.8 on September 10, 2026, fixing 18 vulnerabilities across Community and Enterprise Editions. CVE-2026-85706 allows unauthenticated arbitrary file reads via the repository commits API; CVE-2026-87719 exposes Advanced Search credentials through GraphQL subscription deserialization; CVE-2026-88765 may enable authenticated RCE via crafted project export imports. No exploitation was reported, but self-managed administrators are urged to upgrade immediately and review logs for suspicious API and GraphQL activity.

Critical GitLab GraphQL Flaw Could Let Unauthenticated Attackers Delete Public Projects
GitLab urgently patched CVE-2026-19478 (CVSS 9.4), a critical unauthenticated GraphQL flaw allowing modification or deletion of public projects on self-managed instances.
GitLab released an out-of-band critical patch on August 17, 2026 fixing CVE-2026-19478 (CVSS 9.4), a flaw that under certain conditions lets unauthenticated attackers remotely modify or delete public projects and user data via a GraphQL directive in Community and Enterprise Editions. Fixes are available in GitLab 19.2.4, 19.1.6, 19.0.8, and 18.11.11; GitLab.com and GitLab Dedicated are already patched, so only self-managed installations need to act. The release also fixes CVE-2026-19650 (CVSS 7.1), a cross-site request forgery flaw in GraphQL multiplex query handling requiring user interaction. No exploitation or public exploit code has been observed as of August 18, 2026.

U.S. CISA adds GitLab, JFrog Artifactory, and ConnectWise ScreenConnect flaws to its Known Exploited Vulnerabilities catalog
CISA added four actively exploited GitLab, JFrog Artifactory, and ConnectWise ScreenConnect flaws to the KEV catalog with imminent deadlines.
CISA added CVE-2026-42016 and CVE-2026-42018 (JFrog Artifactory), CVE-2026-84869 (ConnectWise ScreenConnect), and CVE-2026-85706 (GitLab, CVSS 10.0) to its KEV catalog. Artifactory flaws are being chained with CVE-2026-82329 in attacks observed August 15 to September 8, taking over self-hosted servers, creating persistent administrator accounts, and installing backdoors. ScreenConnect CVE-2026-84869 allows unauthorized file transfer and execution during remote sessions, linked by Huntress to malicious VBScript deliveries, and is fixed in version 26.6.5. GitLab's repository commits API path traversal exposes SSH keys, database credentials, deploy tokens, and CI/CD variables, with watchTowr already observing in-the-wild probes. Federal agencies must patch GitLab and ScreenConnect flaws by September 14, 2026, and Artifactory flaws by September 25, 2026.

GitLab Patches Critical Unauthenticated GraphQL Vulnerability
GitLab issued an emergency patch for a critical unauthenticated GraphQL flaw (CVE-2026-19478, CVSS 9.4) enabling remote modification or deletion of public projects.
GitLab patched CVE-2026-19478 (CVSS 9.4), an unauthenticated GraphQL directive flaw allowing remote modification or deletion of public projects and user data on self-managed servers. The emergency patch released August 17 covers versions 19.2.4, 19.1.6, 19.0.8, and 18.11.11, but no fixes exist for the 18.2-18.10 branches. A second issue, a CSRF weakness in GraphQL multiplex queries (CVE-2026-19650, CVSS 7.1), shipped in the same release. No exploitation or public PoC has been observed; the flaw was reported by hiimguardian through HackerOne.

Perfect-10 GitLab bug under attack days after patch lands
CISA confirms active exploitation of CVSS 10.0 GitLab path traversal flaw CVE-2026-85706 days after patches shipped, enabling unauthenticated arbitrary file reads.
CISA added CVE-2026-85706, a maximum-severity 10.0 CVSS path traversal flaw in GitLab's repository commits API, to its Known Exploited Vulnerabilities catalog and confirmed active exploitation. The bug allows unauthenticated attackers to read arbitrary files, including configuration data and credentials, from self-managed GitLab CE/EE servers via a single HTTP POST request. GitLab shipped fixes on September 10 in versions 19.3.2, 19.2.6, and 19.1.8, covering versions 18.7 through 19.3. watchTowr is observing probes against internet-facing instances and warns widespread exploitation is likely to follow quickly.

Critical GitLab flaw allows attackers to modify or delete public projects (CVE-2026-19478)
GitLab patched a critical unauthenticated code injection flaw CVE-2026-19478 (CVSS 9.4) enabling modification or deletion of public projects; upgrades urged.
GitLab released patches for two vulnerabilities affecting Community Edition (CE) and Enterprise Edition (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. CVE-2026-19478 (CVSS 9.4) is an unauthenticated code injection via a GraphQL directive, exploitable remotely without user interaction, allowing attackers to modify or delete public projects and user data. CVE-2026-19650 (CVSS 7.1) is a cross-site request forgery issue in the GraphQL multiplex query handler allowing mutations via GET requests with user interaction. Fixes are available in 18.11.11, 19.0.8, 19.1.6, and 19.2.4; both flaws were reported via GitLab's HackerOne bug bounty program.

GitLab Warns of Active Exploitation of Critical GraphQL Flaw
GitLab emergency-patches actively exploited flaw CVE-2026-19478 (CVSS 9.4), letting unauthenticated attackers modify or delete public projects on self-managed servers.
GitLab emergency-patched CVE-2026-19478 (CVSS 9.4) on August 17 after WatchTowr researchers warned of active exploitation. The flaw lets unauthenticated attackers remotely modify or delete public projects and user data through a GraphQL directive, affecting only self-managed installations. Fixes ship in versions 19.2.4, 19.1.6, 19.0.8, and 18.11.11; the 18.2-18.10 branches receive no patch and must upgrade. Until patching, defenders should restrict unauthenticated access to /api/graphql, disable public repositories, and hunt for @gl_introduced in logs.

GitLab CVE-2026-19478 Comes Under Active Exploitation Within Days of Disclosure
Unauthenticated attackers are actively exploiting GitLab CVE-2026-19478 (CVSS 9.4) to modify or delete public projects days after disclosure.
GitLab CVE-2026-19478, a CVSS 9.4 code injection flaw exploitable via a GraphQL directive without authentication, allows attackers to modify or delete publicly accessible projects, rewrite repository data, forge merge records, and ban maintainers. Affected versions include GitLab CE/EE 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. watchTowr reproduced the flaw within minutes of disclosure and observed in-the-wild exploitation against its honeypot network. Fixes shipped in 19.2.4, 19.1.6, 19.0.8, and 18.11.11; interim mitigations include restricting unauthenticated access to /api/graphql or removing public repository access.
