CVE-2026-115251 Details
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.
A vulnerability in the Duplicator WordPress plugin, affecting versions prior to 5.0.0, allows for unauthorized privilege escalation in multisite environments. The plugin's one-click upgrade feature is exposed without authentication and not restricted to users with the appropriate permissions to install plugins. This flaw enables an administrator of a child site to execute arbitrary PHP code in the shared Duplicator plugin directory across the network.
Users are advised to update the Duplicator WordPress plugin to version 5.0.0 or later.
