GitLab CE/EE versions from 13.6 up to but not including 18.11.6, 19.0 up to 19.0.3, and 19.1 up to 19.1.1 contain an authorization vulnerability. Under certain conditions, an authenticated user with Reporter-level group permissions could view package metadata from projects with the Package Registry disabled. This occurs due to incorrect authorization checks in the group packages feature. The issue has been remediated in versions 18.11.6, 19.0.3, and 19.1.1.
