      "value": "WWBN AVideo is an open source video platform. In versions up to and including 29.0, objects/users.json.php exposes two unauthenticated paths that disclose the full set of registered user accounts. The isCompany request parameter causes the handler to set $ignoreAdmin = true for any non-admin caller (including unauthenticated visitors), which defeats the admin-only guard inside User::getAllUsers()/User::getTotalUsers(). A second path accepts users_id and calls User::getUserFromID() directly with no permission check, producing a single-user oracle. Both paths return id, identification (display name), channel URL, photo, background, and status, plus the total account count. Commit d9cdc702481a626b15f814f6093f1e2a9c20d375 contains an updated fix."

      "value": "WWBN AVideo es una plataforma de vídeo de código abierto. En versiones hasta la 29.0 inclusive, objects/users.json.php expone dos rutas no autenticadas que revelan el conjunto completo de cuentas de usuario registradas. El parámetro de solicitud isCompany hace que el gestor establezca $ignoreAdmin = true para cualquier llamador no administrador (incluidos los visitantes no autenticados), lo que anula la protección solo para administradores dentro de User::getAllUsers()/User::getTotalUsers(). Una segunda ruta acepta users_id y llama a User::getUserFromID() directamente sin verificación de permisos, produciendo un oráculo de un solo usuario. Ambas rutas devuelven id, identificación (nombre de visualización), URL del canal, foto, fondo y estado, además del recuento total de cuentas. El commit d9cdc702481a626b15f814f6093f1e2a9c20d375 contiene una corrección actualizada."
