CVE-2025-5781

Session hijacking via logged REST API tokens

Published Feb 25, 2026 · Updated Feb 25, 2026

Session-token exposure in Hitachi Configuration Manager products allows local users to hijack REST API sessions through log access. Affected REST API components write session tokens used as Authorization credentials into log files instead of excluding the sensitive values. A low-privileged local user who can read those logs can reuse an exposed token to act within another user's live session; no user interaction is required.
