CVE-2024-43580Network attack vector

User-interface spoofing via crafted web content

Published Oct 17, 2024 · Updated Aug 19, 2026

Spoofing in Microsoft Edge (Chromium-based) before 130.0.2849.46 allows remote attackers to mislead users via crafted web content. Microsoft has not published the affected interface or how it fails to warn users about the dangerous operation performed by that content. Exploitation requires a user to view an attacker-controlled page, and the public record does not identify the information exposed or the actions induced.
