CVE-2026-12136
Received Received - Intake
Stored XSS in Customize My Account For WooCommerce Plugin

Publication date: 2026-06-18

Last updated on: 2026-06-18

Assigner: 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.

Executive Summary

The Customize My Account For Woocommerce plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in versions up to and including 4.3.6. This vulnerability arises because the plugin does not properly sanitize or escape user-supplied attributes (min_height, min_width, max_height, max_width) in the 'sysbasics_user_avatar' shortcode. These attributes are concatenated unescaped into the style attribute of the get_avatar() function, allowing an attacker with Contributor-level access or higher to inject malicious scripts that execute whenever a user views the affected page.

Impact Analysis

This vulnerability can allow an authenticated attacker with Contributor-level access or above to inject arbitrary malicious scripts into pages viewed by other users. This can lead to the execution of unwanted scripts in users' browsers, potentially resulting in theft of sensitive information, session hijacking, or other malicious actions that compromise the security and integrity of the affected website.
