CVE-2024-0410Public exploitNetwork attack vector

CODEOWNERS approval bypass via conflict resolution

Published Feb 21, 2024 · Updated Aug 14, 2026

Authorization bypass in GitLab 15.1 through 16.7.5, 16.8 through 16.8.2, and 16.9.0 allows remote authenticated users to bypass CODEOWNERS approval. Conflict resolution accepts an attacker-controlled merge result without invalidating the existing approval when protected files change. Developer access, required Code Owner approval, and a crafted merge conflict are required; exploitation can place unreviewed code on a protected branch and expose protected CI/CD variables.
