CVE-2025-7000Public exploitNetwork attack vector

Confidential branch-name disclosure via issue merge-request links

Published Nov 15, 2025 · Updated Nov 17, 2025

Information disclosure in affected GitLab CE/EE releases allows remote authenticated users to view confidential branch names through project issues. The issue page renders a related merge request's source branch name without enforcing the repository's Only Project Members visibility setting. The path requires a public project, restricted repository visibility, and an issue with a related merge request; only branch names are exposed, including names derived from issue titles.
