CVE-2026-109434 · Sleipnir Browser < 3.9.0 Fullscreen Address Bar Spoofing
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Fenrir Sleipnir Browser for Android before 3.9.0 contains a UI spoofing vulnerability that allows remote attackers to impersonate the browser's trusted address bar by entering fullscreen mode via the Fullscreen API without displaying a persistent notification or trusted-origin indicator. Attackers can render a counterfeit address bar showing a trusted origin over attacker-controlled content after a single user tap, enabling credential harvesting, malware delivery, or social engineering through fake login, update, or payment pages.
