CVE-2025-13478Network attack vector

Cross-user session disclosure via insecure application caching

Published Mar 27, 2026 · Updated Mar 27, 2026

Cache misconfiguration in OpenText Identity Manager 25.2 (v4.10.1) allows remote authenticated users to obtain another user's session data. The application cache fails to keep session data isolated by user, allowing one authenticated session to receive data cached for another. The exposed session data supports victim impersonation and access to that user's data, and exploitation requires an authenticated network session.
