CVE-2026-14814
HIGH 8.2GitLab has remediated an issue in GitLab CE/EE affecting all versions before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed a user to poison cached responses for raw repository files, causing targeted users' CI/CD pipelines to execute specially crafted content and potentially exposing protected environment variables, due to improper validation of repository references.
Severe if exploited (CVSS 8.2), but no known exploitation and low modeled probability. Patch on a normal cadence.
