summary: Authentication bypass in github.com/nanobox-io/golang-nanoauth
description: |-
    If any of the ListenAndServe functions are called with an empty token, token
    authentication is disabled globally for all listeners.

    Also, a minor timing side channel was present allowing attackers with very low
    latency and able to make many requests to potentially recover the token.
