Description

The WP User Frontend plugin for WordPress is vulnerable to privilege escalation due to the default user role checking on the process_registration function in versions up to, and including, 3.5.28 which accepts user supplied input via the urhidden value. This makes it possible for attackers, under certain circumstances, to register as administrators. This requires the attacker have access to the AUTH_KEY and AUTH_SALT values from wp-config.php.
