Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 55

Description The issue is related to the implementation of the WebRTC mechanism in Mozilla Firefox, which fails to protect the structure of web pages. This could potentially allow a remote attacker to conduct cross-site scripting (XSS) attacks. The vulnerability is difficult to exploit because the data is supplied by WebRTC usage and is not under third-party control.

Recommendations For versions prior to 55, update to version 55 or later to resolve the issue. As a temporary workaround, consider restricting access to the "about:webrtc" page until a patch is available. Avoid using the innerHTML property in the affected page to minimize the risk of exploitation.
