Description

The Prime Slider – Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'follow_us_text' setting of the Mount widget in all versions up to, and including, 4.1.10. This is due to insufficient input sanitization and output escaping. Specifically, the `render_social_link()` function in `modules/mount/widgets/mount.php` outputs the `follow_us_text` Elementor widget setting using `echo` without any escaping function. The setting value is stored in `_elementor_data` post meta via `update_post_meta`. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
