Local security-feature bypass via insecure sensitive-data storage
Published Apr 8, 2025 · Updated Aug 10, 2026
Insecure sensitive-data storage in Windows Kerberos allows local authenticated users to bypass a security feature on affected Windows builds. Microsoft identifies insecure storage in the Kerberos component but has not disclosed the stored data, storage locus, or improper access operation. Exploitation requires low-privileged local access; the crossed security boundary and exact data-access consequences remain undisclosed.
