Description
Mozilla developer Ehsan Akhgari reported a spoofing attack where the permission prompt for a WebRTC session can appear to be from a different site than its actual originating site if a timed navigation occurs during the prompt generation. This allows an attacker to potentially gain access to the webcam or microphone by masquerading as another site and gaining user permission through spoofing.
