Enfold <= 6.0.9 - Authenticated (Subscriber+) Server-Side Request Forgery via attachment_id

The Enfold theme for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 6.0.9 via the 'attachment_id' parameter. This makes it possible for authenticated attackers, with Subscriber-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.
