Avada | Website Builder For WordPress & WooCommerce <= 7.16.1 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'author_facebook' User Profile Field
The Avada | Website Builder For WordPress & WooCommerce theme for WordPress is vulnerable to Stored Cross-Site Scripting via the user profile 'Author Page' social link contact-method fields (author_facebook, author_twitter, author_linkedin, author_dribble, author_whatsapp, author_email) in versions up to, and including, 7.16.1. Avada registers these fields through the user_contactmethods filter and, on the author archive, emits them inside an anchor href using only esc_attr() in Fusion_Social_Icon::get_markup(), which escapes HTML metacharacters but does not reject dangerous URL schemes such as javascript:. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses their author page and clicks the injected social icon (a click is required, and the site must have 'Open Social Icons in a New Window' set to Off so the browser doesn't block the javascript: URL from opening in a new tab).
