CVE-2021-29959 is fixed in 4 products on 2 platforms, first by firefox 89.0+build2-0ubuntu0.18.04.2, released June 1, 2021. It is not reported as exploited. Patch Radar priority: Routine.
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.
