What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

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.
