CVE-2025-3073Network attack vector

UI spoofing via undisclosed Autofill flaw

Published Apr 2, 2025 · Updated Apr 15, 2025

Inappropriate Autofill implementation in Google Chrome before 135.0.7049.52 allows remote attackers to spoof browser UI via crafted HTML. Google has not publicly disclosed the faulty Autofill operation; the linked Chromium issue remains restricted and the release note identifies only the affected component. Exploitation requires specific user gestures on the attacker's page, and the resulting false browser presentation can deceive the user but does not interrupt service.
