Local spoofing via attacker-controlled file paths
Published Jun 10, 2025 · Updated Feb 20, 2026
External path control in Microsoft Windows Security App before 1000.27840.1000.0 allows local users to spoof security content. The app accepts an attacker-controlled file name or path, but Microsoft has not published the affected component or the operation that mishandles it. Exploitation requires a locally authorized user and can disclose information through spoofed content; no integrity or availability impact is reported.
