CVE-2026-12136
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.
Summary dbcve.org
The Customize My Account For Woocommerce plugin fails to sanitize user-supplied attributes (min_height, min_width, max_height, max_width) in the sysbasics_user_avatar shortcode's wcmamtx_get_avatar_default() function. These unescaped values are directly concatenated into the get_avatar() function's extra_attr style attribute, allowing authenticated attackers with Contributor-level access to inject persistent malicious scripts.
Mitigation
Upgrade to version 4.3.7 or later, which should include proper input sanitization and output escaping for the affected shortcode attributes.
