Upgrade the Post Duplicator plugin to version 3.0.18 or later, where this vulnerability is fixed. If you cannot patch yet, restrict site administrator privileges on multisite networks to trusted users only.
Description
The Post Duplicator WordPress plugin before version 3.0.18 contains an improper privilege management vulnerability. This flaw allows a site administrator on a multisite network, who is not a Super Admin, to assign arbitrary capabilities to any role via the plugin's permissions settings. This includes network-management capabilities that should be reserved exclusively for Super Admins.
