Descriptions

The UserPro plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.1.1. This is due to missing nonce validation in the 'admin_page', 'userpro_verify_user' and 'verifyUnverifyAllUsers' functions. This makes it possible for unauthenticated attackers to modify the role of verified users to elevate verified user privileges to that of any user such as 'administrator' via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

El complemento UserPro para WordPress es vulnerable a la Cross-Site Request Forgery en versiones hasta la 5.1.1 incluida. Esto se debe a que falta la validación nonce en las funciones 'admin_page', 'userpro_verify_user' y 'verifyUnverifyAllUsers'. Esto hace posible que atacantes no autenticados modifiquen la función de los usuarios verificados para elevar los privilegios de los usuarios verificados a los de cualquier usuario, como "administrador", a través de una solicitud falsificada, siempre que puedan engañar a un administrador del sitio para que realice una acción como hacer clic en un enlace. .
