Overview
CVE-2025-6251 details a stored Cross-Site Scripting (XSS) vulnerability discovered in the Royal Elementor Addons and Templates plugin for WordPress. This vulnerability affects all versions up to and including 1.7.1036. An attacker with Contributor-level access or higher can inject malicious JavaScript code into pages. This code will then execute whenever a user visits the infected page, potentially leading to account compromise, data theft, or other malicious activities.
Technical Details
The vulnerability lies within the $item['field_id'] parameter used by the plugin. Due to insufficient input sanitization and output escaping, an authenticated attacker can inject arbitrary web scripts into form builder components. Specifically, the lack of proper validation allows malicious code to be saved within the WordPress database. This stored XSS vulnerability is triggered when an administrator or other user views the page containing the crafted form element.
The vulnerable code is located within the wpr-form-builder.php file, as seen in the plugin’s source code.
