What is a WebRTC leak?
A WebRTC leak is a vulnerability that can occur in web browsers like Firefox, Google Chrome, Brave, Opera, and others. A WebRTC leak presents a major security risk, as it can can expose your real IP address when you’re connected to a subpar VPN that doesn’t protect you against WebRTC leaks.
What is WebRTC?
WebRTC (Web Real-Time Communication) is an open-source tool that allows web browsers to form real-time peer-to-peer connections with the websites they visit.
This allows your Firefox browser, for example, to send live audio and video feeds back and forth between you and another participant online without having to download any additional software. This is a non-proprietary protocol that allows any website to plug in and make such a connection (with your permission).
WebRTC does this by establishing special real time communication channels from the browser. They communicate with the website you’re visiting and exchange information (including your local and public IP addresses).
