Reflected Cross-Site Scripting in SysBasics Customize My Account for WooCommerce

Publication date: 2026-06-18

Last updated on: 2026-06-18

Assigner: Wordfence

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.

Executive Summary

The SysBasics Customize My Account for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting (XSS) via the 'tab' parameter in all versions up to and including 4.3.6. This vulnerability arises due to insufficient input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts.

However, exploitation requires the victim to be logged in with Shop Manager-level access or higher because the vulnerable function is only rendered within the WordPress admin dashboard.

Impact Analysis

If exploited, this vulnerability allows attackers to inject malicious scripts that execute in the context of the victim's browser session. This can lead to theft of sensitive information, session hijacking, or performing unauthorized actions on behalf of the victim.

Since the attack requires the victim to have Shop Manager-level access or higher, the impact is limited to users with elevated privileges, potentially compromising administrative functions within the WordPress site.
