We are able to spoof the address bar with WebAuthn Attestation prompt since it hides the Full Screen Notification.

Steps to reproduce:

  1. Go to https://pwning.click/webauthn2.php

  2. Tap on "START" and "Click here!"

Please note that this has a different root cause to https://bugzilla.mozilla.org/show_bug.cgi?id=1881902 and https://bugzilla.mozilla.org/show_bug.cgi?id=1884642 since they work on both Nightly and Focus while this only works on Nightly.

Flags: sec-bounty?

The impact of this issue is also similar to this High Severity Chrome Full Screen Spoof issue https://issues.chromium.org/issues/40057591 since this is default notification and affect all users regardless of settings, though.
