Origin spoofing via initial-load redirect handling
Published Sep 17, 2024 · Updated Mar 19, 2025
URL spoofing in Mozilla Firefox for Android before 130.0.1 allows remote attackers to display a trusted origin over malicious content. During an initial App Links load, redirect handling attempts to navigate back after a trusted-site redirect chains into an intent URL, leaving the prior origin in the address bar while attacker content remains interactive. Exploitation requires a user to open a trusted site's link in a new tab and that site to provide an open redirect; the resulting spoof can support phishing and misdirect password-manager autofill.
