Local security feature bypass via improper validation
Published Jul 11, 2025 · Updated Feb 20, 2026
Improper input validation in Microsoft Edge before 138.0.3351.55 allows local users to bypass a security feature. Microsoft has not published the affected component, accepted input, or validation operation that enables the bypass. Exploitation requires low-privileged local access and high-complexity conditions, and the published impact is limited to unauthorized integrity changes.
