      "value": "A broken access control vulnerability in Ghost Foundation Ghost 5.x allows authenticated Author-role users to delete posts owned by other users. The post model permissible() cascade is missing the branch that handles the combined isAuthor and isDestroy condition, causing the authorization check to fall through and permit the deletion. An attacker with an Author account can delete any post on the platform."

      "value": "Una vulnerabilidad de control de acceso roto en Ghost Foundation Ghost 5.x permite a usuarios autenticados con rol de Autor eliminar publicaciones de otros usuarios. La cascada “permissible()” del modelo de publicación carece de la rama que maneja la condición combinada “isAuthor” e “isDestroy”, lo que provoca que la verificación de autorización se omita y permita la eliminación. Un atacante con una cuenta de Autor puede eliminar cualquier publicación en la plataforma."
