Description

The Royal Addons for Elementor plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `wpr_update_form_action_meta` AJAX action in all versions up to, and including, 1.7.1056. The handler is registered on both `wp_ajax` and `wp_ajax_nopriv` hooks, making it accessible to unauthenticated users. Although a nonce is verified, the nonce (`wpr-addons-js`) is publicly exposed in frontend JavaScript via `WprConfig.nonce` on any page that loads Royal Addons widgets, rendering the protection ineffective. The endpoint also lacks any capability or ownership checks and directly calls `update_post_meta()` with user-controlled input on a whitelisted set of form action meta keys. This makes it possible for unauthenticated attackers to modify form action configuration metadata (email, submissions, Mailchimp, and webhook settings) on any post, potentially leading to webhook/email action tampering and data exfiltration via modified webhook URLs.
