## Overview

The Prime Mover plugin for WordPress before 2.2.1 contains a stored cross-site scripting vulnerability that allows attackers to execute arbitrary JavaScript by injecting an unescaped site_title value in a package's footprint.json file. Attackers can place a crafted package under the prime-mover-export-files directory so that the malicious value renders unescaped in the column_site_title() method of PrimeMoverBackupMenuListTable.php, triggering script execution in an administrator's browser when they view the Prime Mover Packages list table without needing to restore the package.
