Q: Am I affected by this vulnerability?

You are affected if your site runs Bdthemes Prime Slider Lite.

Q: How do I fix it?

Update Bdthemes Prime Slider Lite to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a Cross-Site Scripting (XSS) flaw. An attacker who exploits it can run script in a visitor's browser, stealing sessions or planting an administrator account.

CVE-2026-4341

Vulnerability CVE-2026-4341 PLUGIN bdthemes-prime-slider-lite MEDIUM

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.
