Description Doran Moppert 2017-08-08 02:50:26 EDT
JavaScript in the `about:webrtc` page is not sanitized properly being being assigned to `innerHTML`. Data on this page is supplied by WebRTC usage and is not under third-party control, making this difficult to exploit, but the vulnerability could possibly be used for a cross-site scripting (XSS) attack.
