HIGH CVE-2026-18405 Deferred

Jeg Kit Countdown scripts activate attacker-supplied comment markup

Jeg Kit for Elementor through 3.2.16 permits unauthenticated stored XSS through comment content, but only when the targeted post also renders a legitimate Jeg Kit Countdown widget. That widget causes its frontend script to load and initialize matching DOM elements, including forged widget markup stored in comments. Attacker-controlled comment markup can therefore reach the widget's executable rendering path when the page is viewed. The export does not disclose the exact malicious attribute, initialization function, submission route, or whether comment approval is needed in a given configuration. It does not establish a moderation bypass. Although the CNA vector records UI:N, script execution still depends on a user viewing the affected content. No fixed version is confirmed.

Weakness
CWE-79 — Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

This CVE was published Sep 18, 2026 and is one of 23 known issues for this plugin.

Update, patch or deactivate.

Update to the latest supported Jeg Kit release, currently 3.2.18, but do not count it as a confirmed fix: the 3.2.17 changelog mentions security issues without identifying Countdown comment XSS. A newer release may resolve the issue; obtain a matching vendor confirmation. Official changelog: https://wordpress.org/plugins/jeg-elementor-kit/#developers . Until fixed, remove Countdown widgets from pages rendering untrusted comments, or disable comment display on those pages. Limit widget initialization to trusted widget roots, strictly validate widget data and escape any output derived from it; do not treat a matching DOM class as proof that markup was generated by the plugin. Remove malicious saved comments.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Technical description

The Jeg Kit for Elementor – Powerful Addons for Elementor, Widgets & Templates for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 3.2.16 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires that the targeted post also renders a legitimate Jeg Kit Countdown widget, which causes the countdown frontend script to be enqueued and to initialize on any matching DOM element — including forged widget markup stored in comments.
