---------------------------------------

             Summary: Non-superuser users should not be able to list users
                 Key: CASSANDRA-7513
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7513
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Mike Adamson
             Fix For: 2.0.10


ListUserStatement allows any logged in user to list all the users in the 
system. This is a security flaw as it allows non-superusers to get a list of 
superusers.

There is no reason to allow non-superusers to get a list users because all the 
authentication functionality that manipulates users is only available to 
superusers.
