Ckeditor security concerns in laravel

I want to let my users post articles on my website but i have serious concerns about ckeditor security.

What i want to ask is:

1. Can users upload any kind of codes that can put my site at risk through ckeditor?
2. Is there any way to limit users of those kind of actions?

About my application:

I'm using laravel 5.6 and ckeditor last version.

Please share your thoughts and experiences.
