Descriptions

When a user has already allowed a website to access microphone and camera, disabling camera sharing would not fully prevent the website from re-enabling it without an additional prompt. This was only possible if the website kept recording with the microphone until re-enabling the camera. This vulnerability affects Firefox < 89.

Cuando un usuario ya ha permitido a un sitio web acceder al micrófono y a la cámara, la desactivación del uso compartido de la cámara no impedía completamente que el sitio web volviera a activarlo sin una solicitud adicional. Esto sólo era posible si el sitio web seguía grabando con el micrófono hasta volver a habilitar la cámara. Esta vulnerabilidad afecta a Firefox versiones anteriores a 89
