Royal Addons for Elementor <= 1.7.1066 - Unauthenticated Sensitive Information Exposure via Unfiltered meta_query LIKE Oracle in 'wpr_keyword' Parameter

The Royal Addons for Elementor – Addons and Templates Kit for Elementor plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.7.1066 via the 'wpr_keyword' parameter. This makes it possible for unauthenticated attackers to extract arbitrary postmeta values from all published posts via character-by-character substring matching across the entire wp_postmeta table. The required nonce is emitted publicly via wp_localize_script on any frontend page that loads a Royal Elementor widget, meaning no authenticated session or prior action is needed to obtain it.
