Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, SessionRequestHandler in the session management endpoint does not enforce ownership or privilege checks when a low-privileged authenticated user queries session information in deployments using stateful session storage. A requester who knows a target identity identifier can retrieve another user's active session credentials, including credentials for a more privileged account, and use them to hijack that session. This issue is fixed in version 16.1.1.

Why it matters

Internet-facing
Not identified as a common internet-facing category
Exploitation likelihood
medium
  • Remotely exploitable over the network — no physical or local access required
  • High attack complexity — exploitation requires specific conditions
  • Requires low-privilege access first
  • No user interaction needed — can be exploited automatically
Recommended mitigation

Apply the vendor patch as soon as it's available or already released. Review and restrict accounts with the privilege level this vulnerability requires.

This analysis is generated from structured CVSS vector data, CISA KEV cross-referencing, and vendor/product category rules — not a manual expert review. Treat it as a starting point, not a substitute for your own assessment.
