Name of the Vulnerable Software and Affected Versions GitLab versions prior to 15.9.8 GitLab versions 15.10.0 through 15.10.7 GitLab versions 15.11.0 through 15.11.3

Description A malicious developer could use a git feature called refs/replace to smuggle content into a merge request which would not be visible during review in the UI.

Recommendations For versions prior to 15.9.8, update to version 15.9.8 or later. For versions 15.10.0 through 15.10.7, update to version 15.10.7 or later. For versions 15.11.0 through 15.11.3, update to version 15.11.3 or later. As a temporary workaround, consider restricting the use of the refs/replace feature until a patch is applied.
