GitLab has remediated an issue in GitLab CE/EE affecting all versions from 17.6 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an authenticated user with maintainer-role permissions to remove certain package registry metadata that package protection rules restrict to higher roles, due to improper authorization checks.
