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

The SmartAIPress WordPress plugin through 1.2.0 does not perform a capability check on one of its AJAX actions and does not validate a user-supplied URL before fetching it server-side, allowing users with subscriber-level access and above to make the site retrieve arbitrary internal or external URLs and read the response, resulting in a full-read Server-Side Request Forgery.
