SysBasics Customize My Account for WooCommerce <= 4.3.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes

Published Jun 18, 2026 · Updated Jun 18, 2026 · Assigned by Wordfence

Description

The Customize My Account For Woocommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sysbasics_user_avatar' shortcode in versions up to, and including, 4.3.6. This is due to insufficient input sanitization and output escaping on user supplied attributes (min_height, min_width, max_height, max_width) in the wcmamtx_get_avatar_default() function, which are concatenated unescaped into the get_avatar() extra_attr style attribute. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
