How the CVE Works:
CVE-2025-22806 is a DOM-based Cross-site Scripting (XSS) vulnerability in Modernaweb Studio’s Black Widgets For Elementor plugin. The issue arises due to improper neutralization of user-supplied input during web page generation. Attackers can inject malicious JavaScript code into the DOM, which is then executed in the context of the victim’s browser. This allows them to steal sensitive information, such as session cookies, or perform actions on behalf of the user. The vulnerability affects versions up to and including 1.3.8 of the plugin. The attack vector is through crafted input that is not properly sanitized before being rendered on the webpage.
