CVE-2023-2464Network attack vector

Origin spoofing via PictureInPicture implementation flaw

Published May 2, 2023 · Updated Feb 13, 2025

Origin spoofing in PictureInPicture in Google Chrome before 113.0.5672.63 allows attackers to falsify an origin via crafted HTML. The public record identifies an inappropriate PictureInPicture implementation but keeps the issue details restricted, so the exact faulty operation is undisclosed. Exploitation requires a user to install a malicious extension and then process attacker-crafted HTML; the bounded result is misleading origin information in the browser's security UI.
