CVE-2025-0652Network attack vector

Internal-note disclosure via review notification emails

Published Mar 13, 2025 · Updated Mar 14, 2025

Incorrect authorization in affected GitLab CE/EE releases allows remote authenticated users to receive confidential internal notes. Review submission emails include internal merge-request notes without verifying that every recipient is a project member authorized to view them. A low-privilege account must submit a merge-request review that emails a non-member; disclosure is limited to the note contents.
