What is CVE-2026-101890?

The Prime Mover plugin for WordPress prior to version 2.2.1 is susceptible to a stored cross-site scripting (XSS) vulnerability. This issue allows attackers to inject arbitrary JavaScript into the application by manipulating the site_title value within a package's footprint.json file. By placing a specially crafted package into the prime-mover-export-files directory, the malicious value can render unescaped in the column_site_title() method of PrimeMoverBackupMenuListTable.php. Consequently, when an administrator accesses the Prime Mover Packages list table, they may unintentionally execute the injected script in their browser, leading to potential hijacking or data exposure.

Affected Version(s)

Prime Mover 0 < 2.2.1
