The Plus Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'carouseldirection' parameter of the Carousel Anything widget in versions up to, and including, 6.4.15 This is due to insufficient output escaping in the render() function, where the carouseldirection value is placed into an unquoted HTML attribute (dir=) allowing attribute injection despite the use of escattr(). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
