The Create global objects user right must only be assigned to Administrators, Service, Local Service, and Network Service. (Cat II impact)

Discussion

Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. Accounts with the "Create global objects" user right can create objects that are available to all sessions, which could affect processes in other users' sessions.
