CVE-2020-6497Network attack vector

Domain spoofing via Omnibox policy bypass

Published Jun 3, 2020 · Updated Aug 4, 2024

Insufficient policy enforcement in Google Chrome for iOS before 83.0.4103.88 allows remote attackers to spoof domains via a crafted URI. The Omnibox fails to enforce an undisclosed policy when it processes the URI, causing the displayed address to misrepresent the active domain. A user must interact with attacker-controlled content, and the documented consequence is deceptive security UI rather than code execution or data access.
