CVE-2026-84358Network attack vector

Address-bar spoofing after renderer compromise

Published Sep 1, 2026 · Updated Sep 2, 2026

Improper privilege management in Google Chrome Downloads before 152.0.7977.75 allows remote attackers to spoof the address bar via crafted HTML. Google has not disclosed the Downloads code path or privilege decision that mishandles the crafted page. Exploitation requires a compromised renderer and user interaction; the result disguises the page location, with no reported sandbox escape or code execution.
