Unauthenticated content spoofing
Published Aug 3, 2026 · Updated Aug 3, 2026
Code injection in Microsoft Edge (Chromium-based) before 151.0.4129.59 allows remote attackers to spoof content over a network. Microsoft has not published the affected component or the wrong code-generation operation performed on untrusted input. Exploitation is unauthenticated but requires user interaction over a network; Microsoft reports spoofing as the consequence.
