Description
The Robokassa payment gateway for Woocommerce plugin for WordPress is vulnerable to Sensitive Information Exposure via the debug log file in all versions up to, and including, 1.9.0, due to the robokassa_payment_DEBUG() function always appending log entries, whatever the debug setting, to a plain-text file at a predictable, web-accessible path inside the plugin directory (data/robokassa_DEBUG.txt). When the second fiscal receipt is enabled, the log records the full receipt data for each order, including the customer's email address, phone number, order total and purchased items, along with raw Robokassa API responses and callback verification errors. This makes it possible for unauthenticated attackers to download the log file and read customers' personal and order information.
