Advisory

Source description from Wordfence Intelligence, credited to Foxyyy.

The WP CarDealer plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.2.16. This is due to the 'WP_CarDealer_User::process_register' function not restricting what user roles a user can register with. This makes it possible for unauthenticated attackers to supply the 'administrator' role during registration and gain administrator access to the site.
