Customize My Account for WooCommerce, CVE-2026-12136

CVE, Research URL: CVE-2026-12136
Home page URL: Security reports for Customize My Account for WooCommerce
Application: Customize My Account for WooCommerce
Published on: Jun 18, 2026
Research 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.
Affected versions: max 4.3.7.
Status: vulnerable
