SMS account disclosure and spending via unchecked proxy

Published Apr 4, 2022 · Updated Aug 2, 2024

Missing authorization in Melograno Venture Studio Amelia before 1.0.48 allows remote authenticated users to read SMS account data. The wpamelia_api AJAX proxy accepts a customer nonce for /notifications/sms and forwards getUserInfo, getPaymentHistory, and testNotification actions without an administrator authorization check. Any logged-in customer can disclose the administrator email, SMS balance, and payment history or spend the balance by repeatedly sending test notifications.
