Information disclosure via response discrepancy
Published Aug 20, 2026 · Updated Aug 25, 2026
Information disclosure in Microsoft Azure Stack HCI allows remote attackers to infer sensitive information over a network via response discrepancies. Microsoft has disclosed only that the service returns observably different responses and maps the flaw to CWE-204; it has not publicly identified the affected request path, comparison point, or specific data exposed. No authentication or user interaction appears in Microsoft's CVSS 3.1 vector, so any network-reachable Azure Stack HCI deployment should be triaged as a remote confidentiality exposure until fuller technical detail is published.

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.
