Description

The Fattura24 plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 8.1.15. This is due to generated order and invoice PDFs being stored in a publicly accessible uploads folder with a predictable file name based on a timestamp, document type and order ID, and being linked directly without any access control. This makes it possible for unauthenticated attackers to guess file names and download other customers' order and invoice documents containing personal and fiscal data.
