Technical details

The plugin does not sanitize and escape category and location title and icon fields before outputting them in HTML page attributes, enabling stored XSS. Users with the plugin-specific listing-management role (lacking unfiltered_html capability) can inject arbitrary JavaScript that persists in the database and executes for any visitor. The vulnerability is fixed in version 1.5.8.
