Read the original description

The Duplicator WordPress plugin before 5.0.0 does not restrict its one-click upgrade routine to users allowed to install Duplicator WordPress plugin before 5.0.0, and additionally exposes the routine without authentication, allowing an administrator of a multisite child site who is not a network administrator to install and run arbitrary PHP in the network-wide shared Duplicator WordPress plugin before 5.0.0 directory.
