Can I block real IP leak by WebRTC in the browser's setting?
-
@DoctorG v5.7.2921.65 w/ Win10 Pro here, still not works even after restarting the browser.
-
@gaorui84 I guess one of your installed extensions in Vivaldi leak the IP.
Tell which extensions are installed in vivaldi://system → extensions → Button Maximise…
-
@DoctorG Not currently in sync with another device as I use Vivaldi on one PC only, dual systems (Win10 and OpenSUSE) not working at the same time, so it cannot be synced at this moment.
-
@gaorui84 What happens in a fresh test profile where your only Setting is the disabled WebRTC?
-
@DoctorG The leak occurs w/ not only Vivaldi, but other browsers as well. Actually, your IP address would be included in the unsecure UDP streams and could be easily captured w/ Wireshark by the peer when you're in a video chat in browser. This has been confirmed in using Omegle's Video Chat years ago and you can find some Youtube videos revealing this fact.

@gaorui84 
-
@gaorui84 Give URLs of explanative videos which show such leak.
-
@gaorui84 What's the max size of the pic that can be uploaded?
-
@gaorui84 Upload to Imgur and post link here.
-
@gaorui84 1MB as i know.
-
@DoctorG Mine was less than 1MB but it was still rejected.
-
-
@DoctorG I have tried disabling all the extensions in my Vivaldi, but the leak still exists unless Disable non-proxied UDP is set.
-
@gaorui84 Then report that UDP leak as a Security issue, describe how to reproduce, at https://vivaldi.com/bugreport/
