This is supposed to be an overly simplified example... not to be used "for realz".How to fix this should IMHO be explained in later tutorials, but as far this one is concerned - it poses no danger to W3Schools' server, nor can one user touch another, so it's fine.

XSS would require persistent storage of an injected script. Is that in any way possible? You could inject a script into your own cookie but that cookie resides on your own machine.
