- Reporter
- Agi Sferro
- Impact
- low
Description
A website that had permission to access the microphone could record audio without the audio notification being shown. This bug does not allow the attacker to bypass the permission prompt - it only affects the notification shown once permission has been granted.
This bug only affects Firefox for Android. Other operating systems are unaffected.
