User-assisted browser security control bypass
Published Mar 22, 2024 · Updated May 3, 2025
Security feature bypass in Microsoft Edge before 123.0.2420.53 allows remote attackers to alter browser-managed content via crafted web content. Microsoft has not published the affected browser component or the incorrect operation that permits the bypass. Exploitation requires a user to open attacker-controlled content; the documented consequence is limited to modification across a changed security boundary.
