The WordPress Video Robot - The Ultimate Video Importer plugin for WordPress is vulnerable to privilege escalation due to insufficient validation on user meta that can be updated in the wpvr_rate_request_result() function in all versions up to, and including, 1.20.0. This makes it possible for authenticated attackers, with subscriber-level access and above, to update their user meta on a WordPress site. This can be leveraged to update their capabilities to that of an administrator.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
