A privilege escalation vulnerability was discovered in GitLab affecting versions 16.8 prior to 16.8.4 and 16.9 prior to 16.9.2. It was possible for a user with custom role of manage_group_access_tokens to rotate group access tokens with owner privileges.
Weakness
Two distinct privileges, roles, capabilities, or rights can be combined in a way that allows an entity to perform unsafe actions that would not be allowed without that combination.
