Local privilege escalation via untrusted search path
Published Jun 9, 2026 · Updated Jun 9, 2026
Untrusted search path in Microsoft Windows Storage allows local users to elevate privileges by influencing a local load operation. Microsoft has not disclosed the affected executable, library, or search sequence, beyond identifying Windows Storage as the component that searches an untrusted path. Exploitation requires existing low privileges, local access, no user interaction, and high-complexity conditions; success gives elevated control over system data and execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
