Branch-name disclosure via missing GraphQL authorization
Published Dec 16, 2024 · Updated Dec 16, 2024
Incorrect authorization in GitLab CE/EE allows remote attackers to read restricted repository branch names through a GraphQL query. The project protectableBranches GraphQL field applies only a global read_project check available to guests instead of enforcing repository visibility. A public project whose repository is restricted to project members is required, and the disclosure is limited to branch names.
