CVE-2026-17123

The Royal Elementor Addons plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including, 1.7.1064 via the Form Builder widget's 'webhook_url' setting. The widget's render() method persists the attacker-controlled URL into the wpr_webhook_url_{widget_id} option on every render (including a Contributor previewing their own draft), and the wpr_form_builder_webhook AJAX handler — registered for both authenticated and unauthenticated callers — reads that option and dispatches the outbound request via the non-safe wp_remote_post(), with no host allowlist, no scheme restriction, and no private/loopback IP filter (the plugin's existing wpr_is_blocked_remote_host / wpr_is_private_or_local_ip helpers are not called on this path). This makes it possible for authenticated attackers, with Contributor-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
