Description

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 16.5 before 18.11.7, 19.0 before 19.0.4, and 19.1 before 19.1.2 that under certain conditions could have allowed an authenticated user to create a repository where the content displayed in the web interface differed from the content available for download, due to improper handling of Git reference name resolution.
