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.
