Descriptions

The Custom User CSS WordPress plugin through 0.2 does not have CSRF check in place when updating its settings, which could allow attackers to make a logged in admin change them via a CSRF attack.

El complemento de WordPress Custom User CSS hasta la versión 0.2 no tiene activada la verificación CSRF al actualizar su configuración, lo que podría permitir a los atacantes hacer que un administrador que haya iniciado sesión los cambie mediante un ataque CSRF.

The Custom User CSS plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.2. This is due to missing or incorrect nonce validation. This makes it possible for unauthenticated attackers to update plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
