Description
The Fattura24 plugin for WordPress is vulnerable to unauthorized access via the Support tab ticket handler in all versions up to, and including, 8.2.0, due to a missing capability check (and missing nonce) in the fatt_24_get_ticket_data function. That function is hooked to an init-time WooCommerce action and handles any POST request with the 'invia' parameter. This makes it possible for unauthenticated attackers to make the site send support requests to Fattura24's help desk in the site's name. These requests use an attacker-chosen reply-to address and include the plugin settings, environment information and the data of any order the attacker names.
