Descriptions

The Brizy Page Builder plugin <= 2.3.11 for WordPress was vulnerable to stored XSS by lower-privileged users such as a subscribers. It was possible to add malicious JavaScript to a page by modifying the request sent to update the page via the brizy_update_item AJAX action and adding JavaScript to the data parameter, which would be executed in the session of any visitor viewing or previewing the post or page.

El plugin Brizy Page Builder versiones anteriores a 2.3.11 incluyéndola, para WordPress era vulnerable a un ataque de tipo XSS almacenado por usuarios con menos privilegios, como un suscriptor. Era posible añadir JavaScript malicioso a una página al modificar la petición enviada para actualizar la página por medio de la acción brizy_update_item AJAX y añadiendo JavaScript al parámetro data, que se ejecutaría en la sesión de cualquier visitante que visualizara o previsualizara el post o la página
