> Key: CASSANDRA-21560
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21560
> Project: Apache Cassandra
> Issue Type: Bug
> Components: Legacy/Core
> Reporter: Francisco Guerrero
> Assignee: Francisco Guerrero
> Priority: Normal
>
> In {{ListPermissionsStatement}} and {{ListRolesStatement}} we perform a role
> check existence before ensuring the logged in user has access to list roles
> or permissions of that user.
> This could allow someone without access to list roles or permissions to check
> for existence of a role in the database, as the error message will show
> {{role foo does not exist}}.
> We should reverse the conditions and perform the validation before performing
> the role check.
