GitLab CI/CD Regex Integer Overflow (CVE-2026-97229)


On October 12, 2026, GitLab released 19.4.2, 19.3.5, and 19.2.8 to fix CVE-2026-97229, an integer overflow in its CI/CD regular-expression handling. The issue was reported through HackerOne by joaxcar. GitLab assigned it a CVSS score of 10.0 and described possible code execution by an unauthenticated user.

The advisory states that CVE-2026-97229 affects GitLab CE and EE from 19.2 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2. GitLab says all deployment types are affected unless stated otherwise. GitLab.com was patched before disclosure, and Dedicated customers do not need to act.

Rapid7 researchers developed an end-to-end PoC that reliably runs arbitrary commands as GitLab’s git operating-system account on the official Linux amd64 gitlab/gitlab-ce:19.4.1-ce.0 image with ASLR enabled. GitLab’s release notes do not report exploitation in the wild occurring at the time of disclosure.
