WordPress Mapplic <= 6.1 / Mapplic Lite <= 1.0 - Authenticated Stored XSS via SVG File Upload

The Mapplic and Mapplic Lite plugins for WordPress are vulnerable to Stored Cross-Site Scripting via arbitrary URL injection in versions up to and including 6.1 and 1.0 respectively. Authenticated users with author-level permissions can inject arbitrary remote URLs for SVG map files. When a user views the map (admin panel or frontend page with shortcode), the browser fetches the SVG via jQuery .load() and inserts it into the DOM. If the SVG contains embedded JavaScript, it executes as XSS.
