CVE-2025-36254Network attack vector

Authentication bypass via improperly encoded DSCLI output

Published Aug 19, 2026 · Updated Aug 20, 2026

Authentication bypass in IBM DS8A00 and DS8900F HMC allows remote attackers to read sensitive information or interrupt service. The HMC improperly encodes DSCLI command output and uses that unsafe representation across an authentication boundary; IBM has not disclosed the exact field or parser. Exploitation is unauthenticated, network-based, and high-complexity; the HMC contains no customer-data files, limiting exposure to HMC information and availability.
