## Description

The SuperFaktura WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.56.1 due to missing nonce validation on the order document action links (sf_invoice_proforma_create, sf_invoice_regular_create, sf_invoice_cancel_create and sf_regen). This makes it possible for unauthenticated attackers to create or regenerate proforma invoices, invoices and credit notes for orders via a forged request, granted they can trick a logged-in shop manager or administrator into clicking a link.
