CVE-2024-3844Network attack vector

UI spoofing via crafted browser extension

Published Apr 17, 2024 · Updated Feb 13, 2025

Inappropriate implementation in Extensions in Google Chrome before 124.0.6367.60 allows remote attackers to spoof browser UI via a crafted extension. Google has not published which Extensions code path or security check mishandles the crafted extension. Exploitation requires user interaction with attacker-controlled extension content, and the reported consequence is deceptive browser UI rather than data access or service interruption.
