WDesignKit WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the WDesignKit WordPress plugin, specifically in the Elementor and Gutenberg widget builders. This issue affects all versions up to and including 1.2.3. The vulnerability arises from inadequate input sanitization and output escaping, allowing authenticated attackers with Contributor-level access or higher to inject arbitrary scripts into custom widgets. These scripts are executed when a user views 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.

Remediation

Users are advised to update the WDesignKit plugin to version 1.2.4 or later, and to recreate any custom widgets to ensure the vulnerability is fully addressed.
