CVE-2026-18405: Jeg Kit for Elementor <= 3.2.16 - Unauthenticated Stored Cross-Site Scripting via Comment Content
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.

Event History
Frequently Asked Questions
Which sites are exposed to exploitation?
Sites running Jeg Kit for Elementor version 3.2.16 or earlier are affected when a targeted post renders a legitimate Jeg Kit Countdown widget. The widget causes its frontend script to initialize matching markup, including forged markup placed in comments.
Does an attacker need an account or user interaction to exploit this issue?
No account or prior privileges are required. An unauthenticated attacker can submit malicious script-bearing content through comments; the script executes when a user accesses the injected page.
What is the practical impact of a successful attack?
An attacker can store arbitrary web scripts in comment content and have them execute in visitors' browsers when they view the affected page. The provided severity vector indicates impacts to confidentiality and integrity, with scope changed.
What configuration condition should be checked during triage?
Identify posts that render a legitimate Jeg Kit Countdown widget, as this is required for exploitation. Also review comments on those posts for forged widget-like markup or suspicious script payloads.
