I am just starting with WebGoat. On their GitHub page [https://github.com/WebGoat/WebGoat], they have this warning posted:
WARNING 1: While running this program your machine will be
extremely vulnerable to attack. You should to disconnect
from the Internet while using this program. [sic]
What does this mean? My naive understanding says that this is run on a localhost, then where lies the vulnerability?
P.S.: It could be better if you could explain this for one just trying to get off the surface, or anyway, I am looking forward to learn, so please enlighten me. Any advice for one starting off is also most welcome. Thank you all!
