Spoofing through undisclosed information exposure
Published Oct 14, 2025 · Updated Feb 22, 2026
Information disclosure in Microsoft Windows File Explorer allows remote attackers to spoof content over a network after user interaction. Microsoft has not published the affected File Explorer locus or the operation that exposes data to untrusted network content. Exploitation requires interaction with attacker-controlled content; the disclosed consequence is sensitive-data exposure enabling spoofing, not modification or service interruption.
