Royal Elementor Addons < 1.7.1070 - Unauthenticated Arbitrary Email Recipient Injection via Form Field ID Shortcodes

The Royal Elementor Addons WordPress plugin before 1.7.1070 does not validate submitted form field values before substituting them into the recipient addresses of its form notification emails, allowing unauthenticated attackers to replace the recipient list and relay attacker-composed email from the site's own domain when a recipient field is configured to echo a submitted value.
