GitLab: authenticated user could spoof merge request authorship
Fix: upgrade to 19.2.7 or later (3 fixed versions below)
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.1 before 19.2.7, 19.3 before 19.3.3, and 19.4 before 19.4.1 that under certain conditions could have allowed an authenticated user to spoof merge request authorship and attribute content to arbitrary existing users on the target instance due to improper reliance on ephemeral cache state during Direct Transfer imports.
