Autofill restriction bypass via crafted HTML

Published Dec 6, 2023 · Updated Feb 13, 2025

Inappropriate implementation in Google Chrome Autofill before 120.0.6099.62 allows remote attackers to bypass restrictions via crafted HTML. Google has not published the affected Autofill code path or the incorrect operation performed on page-controlled input. Exploitation requires a user to open and interact with a crafted page; the published assessment limits the result to unauthorized modification, not data disclosure or service interruption.
