Name of the Vulnerable Software and Affected Versions: golang-nanoauth versions v0.0.0-20160722212129-ac0cc4484ad4 through v0.0.0-20200131131040-063a3fb69896 Description: The issue concerns a global bypass of authentication in the golang-nanoauth library. When the `ListenAndServe` function is called with an empty token, token authentication is disabled globally for all listeners. Additionally, a minor timing side channel is present, which could allow attackers with low latency and the ability to make many requests to potentially recover the token. Recommendations: For golang-nanoauth versions v0.0.0-20160722212129-ac0cc4484ad4 through v0.0.0-20200131131040-063a3fb69896, consider disabling the `ListenAndServe` function when an empty token is provided until a patch is available. Restrict access to the `ListenAndServe` function to minimize the risk of exploitation. Avoid calling `ListenAndServe` with an empty token in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
