Is it dangerous to put a file access 777?

Decided to install CKEDITOR, installed, plugged in, but wrote that the files are not found. Decided some files to give 644 and folders 755, files had sooo much to sort through them all I couldn't, and decided to put all chmod-R 777. whether it is dangerous? The site is on the server
