CVE-2026-69771

Protected data disclosure via link following

Published Sep 8, 2026 · Updated Sep 10, 2026

Improper link resolution in Windows Container Manager Service in Microsoft Windows 11 allows local users to disclose protected data. The service follows a filesystem link before opening a file, redirecting an authorized access to a different local object; Microsoft has not disclosed the affected routine or exact link type. Low-privilege local access is required, no user interaction is needed, and the published impact is limited to confidentiality.
