The Clasifico Listing plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 2.0. This is due to the plugin allowing users who are registering new accounts to set their own role by supplying the listing_user_role parameter. This makes it possible for unauthenticated attackers to gain elevated privileges by registering an account with the administrator role.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
