The Avada (Fusion) Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Form Notification Dynamic-Data action_hook → Media Upload Chain (ID3 Metadata / html_attributes) in all versions up to, and including, 3.16.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that a Fusion Form is embedded on an admin-authored page (granting manage_options context to the Dynamic Data action hook callback), and that a Post Cards element configured to display attachment post types is present on a publicly accessible page so the planted shortcode payload is rendered.
