Description
gopay before 1.5.119 disables TLS certificate verification in defaultClient() in pkg/xhttp/client.go, allowing man-in-the-middle attackers to impersonate payment provider APIs. Attackers can present any certificate to read merchant credentials, signatures and transaction data, and modify payment, refund and order query responses.
