The Listee theme for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.1.6. This is due to a broken validation check in the bundled listee-core plugins user registration function that fails to properly sanitize the user_role parameter. This makes it possible for unauthenticated attackers to register as Administrator by manipulating the user_role parameter during registration.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
