Avada (Fusion) Builder <= 3.16.1 - Unauthenticated Sensitive Information Exposure in 'args[link_target]' Parameter via {user_meta} Dynamic Data Token
The Avada (Fusion) Builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.16.1 via the 'args[link_target]' parameter. This makes it possible for unauthenticated attackers to extract arbitrary user meta values for any user ID, including administrator email addresses, login names, wp_user_level, and WooCommerce customer PII such as billing_email, billing_phone, and billing_address_1. The awb-instagram-nonce required to trigger this endpoint is printed in plaintext in fusionInstagramVars on any page rendering the [fusion_instagram] shortcode, making it harvestable by any anonymous visitor before the exploit request is sent.
