Details

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.

Severity ?
6.4 (Medium)
