On September 10, 2026, GitLab released patches for critical vulnerabilities CVE-2026-85706 and CVE-2026-87719. CVE-2026-85706, a path traversal flaw, allows unauthenticated users to read arbitrary files from GitLab servers, while CVE-2026-87719 enables credential theft via insecure deserialization. Both vulnerabilities affect GitLab Community Edition (CE) and Enterprise Edition (EE) versions from 18.7 up to 19.3.2. Just one day after the patches were released, threat intelligence firm WatchTowr reported active exploitation attempts targeting CVE-2026-85706. Organizations running self-managed GitLab instances are urged to upgrade immediately, as the vulnerabilities can expose sensitive data and configurations. The situation is critical, with the potential for widespread exploitation expected soon.
