How to fix?

A fix was pushed into the master branch but not yet published.

Overview is a package for image run by build pods to execute image building+pushing.

Affected versions of this package are vulnerable to Insufficient Hostname Verification. Builds that extract source from a container image can bypass the TLS host-name verification server identity check to ensure that the client is talking to the correct server and has not been redirected by a man in the middle attacker.
