How to fix?

Upgrade urllib3 to version 1.24.2 or higher.

Overview

urllib3 is a HTTP library with thread-safe connection pooling, file post, and more.

Affected versions of this package are vulnerable to Improper Certificate Validation. It mishandles certain cases where the desired set of CA certificates is different from the OS store of CA certificates. This can result in SSL connections succeeding in situations where it should have failed.
