Royal Elementor Addons plugin for WordPress vulnerabilities

The Royal Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via the 'status' parameter in the wpr_update_form_action_meta AJAX action in all versions up to and including 1.7.1056. This is due to insufficient input sanitization and output escaping, combined with a publicly leaked nonce that allows unauthenticated access to the AJAX handler.

The Royal Elementor Addons plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to and including 1.7.1057. The issue is due to insufficient validation of user-supplied URLs in the render_csv_data() function.

The Royal Elementor Addons plugin for WordPress is vulnerable to unauthenticated API key disclosure in versions up to and including 1.3.70. The API key is added to the source code of any page running the MailChimp block, allowing unauthenticated attackers to obtain the MailChimp API key.
