Form Maker by 10Web is a widely used WordPress plugin that allows users to easily create and manage forms for a variety of purposes, such as contact forms, surveys, and registration forms. However, a critical Stored Cross-Site Scripting (XSS) vulnerability, CVE-2024-13605, has been discovered in the plugin. This vulnerability allows attackers with editor-level access to inject malicious JavaScript into the “Width” field in the theme settings. When this setting is saved, the malicious script is stored and executed in the browser of any user who hovers over the input field, potentially leading to account takeover and the creation of backdoor admin accounts. With over 50,000 active installations, this flaw poses a serious security risk to WordPress websites using Form Maker.
