Impact

Harbor fails to validate the user permissions when updating a robot account that
belongs to a project that the authenticated user doesn’t have access to. API call:

PUT /robots/{robot_id}

By sending a request that attempts to update a robot account, and specifying a robot
account id and robot account name that belongs to a different project that the user
doesn’t have access to, it was possible to revoke the robot account permissions.

Patches

This and similar issues are fixed in Harbor v2.5.2 and later. Please upgrade as soon as possible.
