CVE-2024-8650Public exploitNetwork attack vector

Unauthenticated internal-note disclosure via new-issue route

Published Dec 16, 2024 · Updated Dec 16, 2024

Incorrect authorization in affected GitLab CE/EE releases allows remote attackers to read internal-note threads in public merge requests. The new-issue route accepts merge_request_to_resolve_discussions_of and renders unresolved internal discussions without enforcing project membership. A public project and known merge-request identifier are sufficient; no account is required, and exposure is limited to confidential note content.
