CVE-2025-49728

Local information disclosure via cleartext storage

Published Sep 16, 2025 · Updated Sep 16, 2025

Cleartext storage in Microsoft PC Manager before 3.18.0.0 allows local users to read sensitive information and bypass a security feature. The application stores unspecified sensitive information without encryption, but Microsoft has not identified the datum, file, registry location, or responsible component. Exploitation requires local access but no prior privileges or user interaction, and the reported consequence is limited disclosure rather than modification or service interruption.
