Description
Summary
Description
An insufficient authorization (CWE-285) and information exposure (CWE-200) issue in OpenAM's session management endpoint allows a low-privileged authenticated user to retrieve active session credentials belonging to other users, including those with higher privileges. This affects OpenAM Community Edition through version 16.0.6 and was patched in version 16.1.1.
This may be related to CVE-2021-4201, a similar issue patched in ForgeRock Access Management, a separate product sharing a common codebase ancestry.
Impact
OpenAM Community Edition deployments through version 16.0.6 using stateful session storage and exposing the session management endpoint are potentially affected. The endpoint does not enforce ownership or privilege checks when querying session information, meaning an authenticated user may retrieve active session credentials for arbitrary users. Successful exploitation requires a valid low-privilege session and knowledge of a target user's identity identifier, which may be obtainable through normal platform functionality.
If credentials belonging to a highly privileged account are obtained, this could enable further administrative actions within the platform
Patch
This has been patched in OpenAM Community Edition version 16.1.1. Users are encouraged to update to the latest release.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.openidentityplatform.openam:openam-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.openidentityplatform.openam:openam-core to 16.1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-45048 is resolved across your whole dependency graph.
Workarounds
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
