Privilege escalation through undisclosed browser flaw
Published Aug 26, 2021 · Updated Aug 10, 2026
Elevation of privilege in Microsoft Edge (Chromium-based) before 92.0.902.55 allows local users to gain elevated privileges. Microsoft has not disclosed the affected browser component or the operation that mishandles untrusted input.
