Local information disclosure via risky cryptography
Published Apr 8, 2025 · Updated Aug 10, 2026
Risky cryptography in Windows Server 2022 Cryptographic Services before build 10.0.20348.3453 allows local users to disclose information. Microsoft has not disclosed the cryptographic primitive, code locus, input, or incorrect operation that produces the disclosure. Low-privileged local access is required, and the published impact is limited to reading otherwise protected information.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
