CVE-2022-3047Network attack vector

Downloads policy bypass via malicious extension HTML

Published Sep 26, 2022 · Updated May 22, 2025

Insufficient policy enforcement in Google Chrome before 105.0.5195.52 allows attackers to bypass downloads policy through a crafted HTML page. The Extensions API fails to enforce the configured downloads restriction, but Google has not published the affected function or check. Exploitation requires a user to install a malicious extension and load attacker-controlled HTML; the bounded consequence is an unauthorized download.
