## Description

The Wallet System for WooCommerce plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the wallet transaction export (PDF/CSV) handler in versions 2.2.8 up to, and including, 2.7.10. The handler runs on every request. Before version 2.5.10 it checked no nonce at all; from 2.5.10 it was protected only by a nonce created with the generic default action, which any logged-in user receives on the plugin's My Account wallet pages. This makes it possible for authenticated attackers, with Subscriber-level access and above, to export the wallet transactions of all users, including names, email addresses, roles and amounts.
