No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

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.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
