It should instead be restricted to only the hosts dedicated to that admin's domain.\n\n\n\n\nThis issue affects Apache CloudStack: from 4.12.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0.\n\n\n\n\nUsers are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.",
