Advisory
Source description from Wordfence Intelligence.
The Post Duplicator plugin for WordPress is vulnerable to Cross-Site Scripting in versions up to, and including, 2.16 due to insufficient input sanitization and output escaping on the 'post-duplicated' parameter. This makes it possible for attackers to inject arbitrary web scripts that execute in a victim's browser.
