Local spoofing via attacker-controlled file paths
Published Aug 12, 2025 · Updated Feb 13, 2026
External path control in Microsoft Windows Security App before 1000.27840.1000.0 allows local users to spoof trusted content. The published record says attacker-controlled file names or paths reach a filesystem operation, but Microsoft has not identified the affected function or missing validation. Low-privilege local access is required, and the reported consequence is confidential-data exposure without integrity or availability impact.

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.
- Affected versionversion=1000.0.0.0 <1000.27840.1000.0
