How the CVE Works:
CVE-2025-26772 is a critical Stored Cross-Site Scripting (XSS) vulnerability in DethemeKit For Elementor, a WordPress plugin. The flaw arises due to improper neutralization of user-supplied input during web page generation. Attackers can inject malicious JavaScript code into the application, which is then stored and executed when other users access the affected page. This allows attackers to steal sensitive information, such as session cookies, or perform actions on behalf of authenticated users. The vulnerability affects all versions up to and including 2.1.8. Exploitation requires no authentication, making it highly dangerous for websites using the plugin.
