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.
