Descriptions

The WP Quick FrontEnd Editor plugin for WordPress is vulnerable to page content injection in versions up to, and including, 5.5. This is due to missing capability checks in the plugin's page-editing functionality. This makes it possible for low-authenticated attackers, such as subscribers, to edit/create any page or post on the blog.

El plugin WP Quick FrontEnd para WordPress es vulnerable a la inyección de contenido de páginas en versiones hasta la v5.5 inclusive. Esto se debe a la falta de comprobaciones en la funcionalidad de edición de páginas del plugin. Esto hace posible que atacantes poco autenticados, como los suscriptores, editen/creen cualquier página o entrada en el blog.
