Remote content spoofing after user interaction
Published Sep 2, 2021 · Updated Aug 10, 2026
Content spoofing in Microsoft Edge (Chromium-based) before 93.0.961.38 allows remote attackers to falsify browser content after user interaction. Microsoft has not published the affected component or the operation that incorrectly handles attacker-controlled input. Exploitation requires user interaction, but the record does not identify the content that can be falsified or the subsequent action an attacker can induce.
