Local privilege escalation through undisclosed mechanism
Published Apr 27, 2023 · Updated Feb 28, 2025
Elevation of privilege in Microsoft Edge before 111.0.1661.54 allows local users to gain elevated privileges via unspecified vectors. Microsoft has not published the affected component or the incorrect operation that permits the privilege boundary to be crossed. The attack needs local execution but no prior privileges or user interaction, and it can disclose data and permit limited modification without affecting availability.
