Security configuration changes via disabled-feature authorization bypass
Published Jun 11, 2026 · Updated Jun 11, 2026
Incorrect authorization in affected GitLab EE releases allows remote authenticated users to alter project security configuration. The authorization check for Security Manager-role permissions permits management operations when the controlling feature is disabled, but GitLab has not disclosed the specific function or endpoint. Exploitation requires an authenticated account with Security Manager-role permissions and is limited to unauthorized configuration changes within accessible projects.
