Description
The WP GPX Maps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via GPX waypoint descriptions shown in the waypoint popups of the Leaflet map engine in all versions up to, and including, 1.14.00. This is due to the map script passing the waypoint description through unescape() before inserting it into the popup HTML, which decodes percent-encoded characters that server-side HTML escaping leaves untouched. This makes it possible for authenticated attackers with contributor-level access and above to inject arbitrary web scripts by placing the [sgpx] shortcode with waypoints enabled and pointing it to a crafted GPX file, for example a remote one. The scripts execute when a user opens the waypoint popup on a page that displays the map.
