CVE-2023-4764Network attack vector

Omnibox spoofing via BFCache security UI mismatch

Published Sep 5, 2023 · Updated Feb 13, 2025

Incorrect security UI in Chrome before 116.0.5845.179 allows remote attackers to spoof the Omnibox through a crafted HTML page. The public record identifies BFCache security UI as the locus but does not disclose which cached-navigation state is handled incorrectly. A user must interact with the crafted page, after which the displayed address can falsely represent the page's origin.
