CVE-2024-38219Network attack vector

Unauthenticated remote code execution

Published Aug 8, 2024 · Updated Jul 10, 2025

Type confusion in Microsoft Edge (Chromium-based) before 127.0.2651.98 allows remote attackers to execute code via network input. Microsoft identifies incompatible-type resource access but has not published the affected component, code path, or malformed input that triggers it. The attack requires no privileges or user interaction but has high complexity; successful exploitation runs code in another security context.
