Shortcodes Ultimate <= 5.12.6 - Authenticated (Subscriber+) Server-Side Request Forgery

The Shortcodes Ultimate plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including, 5.12.6. This is due to insufficient validation on the url being supplied via the "url" attribute of the su_csv_table shortcode. This makes it possible for authenticated attackers, with subscriber-level privileges 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.
