Authenticated data disclosure via externally accessible files
Published Sep 8, 2026 · Updated Sep 9, 2026
Information exposure in Microsoft Windows Search on affected Windows 11 and Windows Server builds allows remote authenticated users to disclose data. The component places unspecified sensitive information in an externally accessible file or directory; Microsoft has not identified the file, data, or triggering operation. Exploitation requires low-privileged access and user interaction, and the documented consequence is network disclosure without integrity or availability impact.
