The Plus Addons for Elementor – Addons for Elementor, Page Templates, Widgets, Mega Menu, WooCommerce <= 6.4.7 - Unauthenticated Email Relay
The The Plus Addons for Elementor – Addons for Elementor, Page Templates, Widgets, Mega Menu, WooCommerce plugin for WordPress is vulnerable to Insufficient Verification of Data Authenticity in all versions up to, and including, 6.4.7. This is due to the plugin decrypting and trusting attacker-controlled email_data in an unauthenticated AJAX handler without cryptographic authenticity guarantees. This makes it possible for unauthenticated attackers to tamper with form email routing and redirection values to trigger unauthorized email relay and attacker-controlled redirection via the 'email_data' parameter.
