Description

The Nias Course Builder plugin for WordPress is vulnerable to Server-Side Request Forgery via the url parameter of the nias_spotplayer_sync AJAX action in all versions up to, and including, 1.3.3, due to the nias_spotplayer_sync_handler() function passing a user-supplied URL to wp_remote_get() without restricting the host or blocking internal addresses. This makes it possible for authenticated attackers with Shop Manager-level access and above to make web requests to arbitrary locations from the web application, including internal services, and read the text of list items in the response.
