  - An authenticated user may be able to view session metadata belonging to other users on the system
    through the $listSessions aggregation stage. This information is normally restricted to users with
    cluster-level administrative privileges, and includes active session identifiers, associated usernames,
    and activity timestamps. (CVE-2026-13061)
