Descriptions
The wp-mpdf plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.5.1. This is due to missing or incorrect nonce validation on the mpdf_admin_savepost() function. This makes it possible for unauthenticated attackers to save post data via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
El plugin wp-mpdf para WordPress es vulnerable a ataques de tipo Cross-Site Request Forgery en versiones hasta la 3.5.1 inclusive. Esto es debido a la falta o incorrecta validación nonce en la función "mpdf_admin_savepost()". Esto hace posible que atacantes no autenticados guarden los datos POST a través de una petición manipulada, lo que les permite engañar a un administrador del sitio para que realice una acción, como hacer clic en un enlace.
