Project information disclosure via missing authorization
Published Jun 25, 2026 · Updated Jun 25, 2026
Missing authorization in GitLab EE 18.6 through 18.11.5, 19.0 through 19.0.2, and 19.1.0 allows remote authenticated users to read project data. The Security Dashboard omits required authorization checks before returning project information, but GitLab has not disclosed the affected handler or exact conditions. Exploitation requires a limited-permission account and unspecified conditions; the published impact is read-only, with no reported data changes or service interruption.
