Critical GitLab flaw CVE-2026-97229 allows code execution and is now on CISA's exploited list

has fixed CVE-2026-97229, an integer overflow in its CI/CD regular-expression handling that carries a CVSS score of 10.0. A Rapid7 proof of concept showed that an attacker who can commit a malicious CI configuration and a crafted path to a public project can run OS commands as the git user on self-managed instances. CISA added the flaw to its Known Exploited Vulnerabilities catalogue on 29 October 2026, so self-managed administrators should upgrade without waiting for the normal patch cycle.
