      "value": "WWBN AVideo is an open source video platform. Prior to version 29.0, Privilege Escalation is possible through unguarded permission parameters in signUp API, which allows any user who can solve a CAPTCHA to self-grant elevated permissions during account registration. The set_api_signUp method in the API plugin accepts emailVerified, canUpload, canStream, and canCreateMeet parameters from user-supplied input and applies them to newly created accounts without verifying that the request was authenticated with a valid APISecret. By self-granting account attributes, attackers can mark their own accounts as email-verified without owning the address (bypassing email-gated functionality) and award themselves upload, streaming, and meeting-creation permissions, circumventing administrator access controls that intentionally restrict these capabilities for new users. This issue has been fixed in version 29.0"

      "value": "WWBN AVideo es una plataforma de video de código abierto. Antes de la versión 29.0, la escalada de privilegios es posible a través de parámetros de permisos desprotegidos en la API de signUp, lo que permite a cualquier usuario que pueda resolver un CAPTCHA auto-otorgarse permisos elevados durante el registro de la cuenta. El método set_api_signUp en el plugin de la API acepta los parámetros emailVerified, canUpload, canStream y canCreateMeet de la entrada proporcionada por el usuario y los aplica a las cuentas recién creadas sin verificar que la solicitud fue autenticada con un APISecret válido. Al auto-otorgarse atributos de cuenta, los atacantes pueden marcar sus propias cuentas como verificadas por correo electrónico sin poseer la dirección (eludiendo la funcionalidad restringida por correo electrónico) y otorgarse a sí mismos permisos de carga, transmisión y creación de reuniones, eludiendo los controles de acceso del administrador que restringen intencionalmente estas capacidades para los nuevos usuarios. Este problema ha sido solucionado en la versión 29.0"
