      "value": "The Meta Box AIO plugin for WordPress is vulnerable to Missing Authorization via the template_redirect dispatcher in the MB Frontend Submission extension in versions up to, and including, 3.8.0. This is due to the handle_request() function routing the mbfs_delete action without any capability or ownership check, and the nonce verification in check_ajax() being gated behind is_ajax() which is false for template_redirect requests, making it bypassable. This makes it possible for unauthenticated attackers to delete arbitrary posts and pages by supplying an attacker-controlled post ID via the rwmb_frontend_field_object_id GET parameter on any page that hosts a frontend submission form regardless of whether allow_delete is enabled."

      "value": "El plugin Meta Box AIO para WordPress es vulnerable a la falta de autorización a través del despachador template_redirect en la extensión MB Frontend Submission en versiones hasta la 3.8.0, inclusive. Esto se debe a que la función handle_request() enruta la acción mbfs_delete sin ninguna verificación de capacidad o propiedad, y la verificación de nonce en check_ajax() está protegida por is_ajax(), que es falso para las solicitudes template_redirect, lo que la hace eludible. Esto hace posible que atacantes no autenticados eliminen publicaciones y páginas arbitrarias al proporcionar un ID de publicación controlado por el atacante a través del parámetro GET rwmb_frontend_field_object_id en cualquier página que aloje un formulario de envío de frontend, independientemente de si allow_delete está habilitado."
