ElementsKit Elementor Addons Stored Cross-Site Scripting Vulnerability in WordPress

A stored cross-site scripting vulnerability has been identified in the ElementsKit Elementor Addons plugin for WordPress, affecting all versions through 3.4.0. The issue arises in the Image Accordion widget, where insufficient input sanitization and output escaping on user-supplied attributes allow authenticated attackers with contributor-level access and above to inject arbitrary scripts. These scripts are executed when a user accesses the affected page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Reproduction

To reproduce this vulnerability, an authenticated user with contributor-level access or higher can use the Image Accordion widget in the ElementsKit Elementor Addons plugin. After injecting a script through the widget's settings, the script will be executed when the page is viewed.

Remediation

Users are advised to update the ElementsKit Elementor Addons plugin to version 3.4.1 or later.
