Server Running as Root error

Every time I start up my server, I get this warning from paper.

YOU ARE RUNNING THIS SERVER AS AN ADMINISTRATIVE OR ROOT USER. THIS IS NOT ADVISED.
YOU ARE OPENING YOURSELF UP TO POTENTIAL RISKS WHEN DOING THIS.
FOR MORE INFORMATION, SEE Why you shouldn't run a Minecraft server as root | Me4502

I looked into this more in depth, and it seems like there are security risks. Is this something I have to worry about on my server? And if so, how do I secure it. I am launching the server from the webui.

ensure when you log into the webui to not log in as root.
