The UserPlus plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 2.0 due to insufficient restriction on the form_actions and userplus_update_user_profile functions. This makes it possible for unauthenticated attackers to specify their user role by supplying the role parameter during a registration.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
