CVE-2026-79233Network attack vector

Address-bar spoofing via crafted Custom Tab

Published Aug 25, 2026 · Updated Aug 25, 2026

UI misrepresentation in Google Chrome for Android before 152.0.7977.65 allows remote attackers to spoof the address bar via crafted HTML. The flaw occurs in CustomTabs, but Google has not published how crafted page content causes the displayed address-bar identity to diverge from the loaded page. The attacker must supply crafted HTML to an affected Android Custom Tab; the reported consequence is origin deception, not code execution or data access.
