    Published: 4 Apr 2017Last Modified: 8 Jul 2026

    Summary:

    Details: The Go SSH library (x/crypto/ssh) by default does not verify host keys, facilitating man-in-the-middle attacks. Default behavior changed in commit e4e2799 to require explicitly registering a hostkey verification mechanism.
