Privilege elevation through undisclosed web-content flaw

Published Feb 7, 2022 · Updated Jan 2, 2025

Elevation of privilege in Microsoft Edge before 98.0.1108.43 allows remote attackers to gain elevated privileges through crafted web content. Microsoft has not published the affected component or the operation it performs incorrectly when processing that content. Exploitation requires a user to open attacker-controlled content, and the resulting privilege scope beyond the browser context is not publicly specified.
