Auth bypass in Linuxfoundation Harbor
CVE-2022-31667
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. 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.
