SmartAIPress <= 1.2.0 - Subscriber+ Server-Side Request Forgery via smartaipress_openai_upload_and_set_featured_image

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.
