CVE-2026-45048 (GCVE-0-2026-45048)

Vulnerability from cvelistv5 – Published: 2026-09-15 09:48 – Updated: 2026-09-15 09:48

Title

OpenAM Authenticated Privilege Escalation via Raw Token Disclosure Session RPC

Summary

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.

Severity

8.5 (High)

Vulnerability from github – Published: 2026-06-23 17:33 – Updated: 2026-06-23 17:33

Summary

OpenAM Authenticated Privilege Escalation via Raw Token Disclosure Session RPC

Details

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.

Severity

8.5 (High)
