Descriptions

The All Users Messenger WordPress plugin through 1.24 does not prevent non-administrator users from deleting messages from the all-users messenger.

El plugin All Users Messenger WordPress hasta la versión 1.24 no impide a los usuarios no administradores borrar mensajes del mensajero para todos los usuarios.

The All Users Messenger plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 1.24 due to missing validation on a user controlled key. This can allow authenticated attackers with subscriber access to delete arbitrary messages.
