How to fix?

Upgrade serverpod_client to version 1.2.6 or higher.

Overview

serverpod_client is an open-source, scalable app server

Affected versions of this package are vulnerable to Improper Certificate Validation for all non HTTP traffic. An attacker in a man-in-the-middle position can intercept and hijack encrypted traffic between the client device and the server, due to an ineffective TLS check in serverpod_client_io.dart.
