Descriptions

The ContentStudio plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on several functions in versions up to, and including, 1.2.5. This makes it possible for unauthenticated attackers to obtain the blog metadata (via the function cstu_get_metadata) that includes the plugin's contentstudio_token. Knowing this token allows for other interactions with the plugin such as creating posts in versions prior to 1.2.5, which added other requirements to posting and updating.

El complemento ContentStudio para WordPress es vulnerable a la omisión de autorización debido a una falta de verificación de capacidad en varias funciones en versiones hasta la 1.2.5 incluida. Esto hace posible que atacantes no autenticados obtengan los metadatos del blog (a través de la función cstu_get_metadata) que incluye el contentstudio_token del complemento. Conocer este token permite otras interacciones con el complemento, como crear publicaciones en versiones anteriores a la 1.2.5, lo que agregó otros requisitos para la publicación y actualización.
