EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 83% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
