Fix not verifiedIn the System → Maintenance tool, the Logged Users tab surfaces sessionId data for all users via the Direct Web Remoting API (UserSessionAjax.getSessionList.dwr) calls. While this is information that would and should be available to admins who possess "Sign In As" powers, admins who otherwise lack this privilege would still be able to utilize the session IDs to imitate other users. While this is a very small attack vector that requires very high permissions to execute, its danger lies principally in obfuscating attribution; all Sign In As operations are attributed appropriately in the log files, and a malicious administrator could use this information to render their dealings untraceable — including those admins who have not been granted this ability — such as by using a session ID to generate an API token.

The application performs an authorisation check, but it does not correctly enforce the required permission boundary.
An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may gain additional privileges.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-863: Incorrect Authorization. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
