The SuperFaktura WooCommerce plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.40.3 via the wc_sf_url_check function. 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.
