The Duplicator plugin for WordPress is vulnerable to Cross-Site Scripting in versions up to, and including, 0.5.26 due to insufficient input sanitization and output escaping. This makes it possible for administrator-level attackers to inject arbitrary web scripts that execute in a victim's browser.
