golang.org/x/crypto/ssh Man-in-the-Middle attack
The Go SSH library (golang.org/x/crypto/ssh) by default does not verify host keys, facilitating man-in-the-middle attacks if ClientConfig.HostKeyCallback is not set. Default behavior changed in commit e4e2799 to require explicitly registering a hostkey verification mechanism.
