The Animation Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'weatherstyle' and 'movedirection' parameters of the Weather widget in all versions up to, and including, 2.6.3. This is due to insufficient output escaping in the Weather widget's render() function at widgets/weather.php:1246, where both settings values are placed into an HTML class attribute without escattr(). Elementor does not server-side validate widget SELECT control values against allowed options on save, so an authenticated attacker with Contributor-level access or above can submit a crafted savebuilder AJAX request storing arbitrary values in the elementordata post meta. The stored payload renders unescaped on every frontend visit to the affected page (the Weather widget requires an OpenWeatherMap API key to reach the vulnerable output, which is the normal operational state for sites using this widget).
