CVE-2024-38093Network attack vector

Content spoofing via addressless Picture-in-Picture windows

Published Jun 20, 2024 · Updated Aug 10, 2026

Spoofing in Microsoft Edge (Chromium-based) before 126.0.2592.68 allows remote attackers to misrepresent web content to users. On macOS, a crafted page can open attacker-controlled content in a Picture-in-Picture window that lacks normal address-bar origin cues. A user must visit the page and interact with the deceptive window; successful exploitation changes only the integrity of displayed information.
