CVE-2026-97229
GitLab Community Edition and Enterprise Edition contain a integer overflow or wraparound vulnerability that could allow an unauthenticated user to execute arbitrary code on the GitLab server via a specially crafted regular expression in a CI/CD configuration, due to insufficient regular expression validation.
