CVE-2026-12137
Description
The SysBasics Customize My Account for WooCommerce – Dashboard, Endpoints, Avatar & Menu Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'tab' parameter in all versions up to, and including, 4.3.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Because the vulnerable plugin_options_page() function is only rendered within the WordPress admin dashboard, successful exploitation requires the targeted victim to be logged in with Shop Manager-level access or higher.
Summary dbcve.org
This is a reflected XSS vulnerability in the SysBasics Customize My Account for WooCommerce plugin where the 'tab' parameter in the admin settings page is not sanitized before output, allowing injection of arbitrary JavaScript. The attack requires the victim to be logged in with Shop Manager-level access or higher and tricking them into clicking a malicious link.
Mitigation
Update the plugin to version 4.3.7 or later which includes proper sanitization of the 'tab' parameter using WordPress sanitization functions and output escaping.
