A collision in access memoization logic in all versions of GitLab CE/EE before 14.3.6, all versions starting from 14.4 before 14.4.4, all versions starting from 14.5 before 14.5.2, leads to potential elevated privileges in groups and projects under rare circumstances

Weakness

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
