> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Ivan Andika
> Assignee: Huang Kuan Hao
> Priority: Major
> Labels: pull-request-available
>
> Found a possible security issue where OmClientRequest#getUserInfoNotExists
> might user an admin user (OM starter user) privilege if the client does not
> specify any user info. The current usage is for internal Ozone background
> service like OM Trash emptier and I don't think normal clients will gain
> admin user currently since both Hadoop RPC and gRPC clients should already
> have the user info. However, I think it's best to be defensive and for
> getUserInfoNotExists to not fallback to the admin user since if we make any
> changes in getUserInfo that causes userInfo's remoteAddress and userInfo's
> username to not be set, it might cause cause privilege escalations.
