And what should these precautions be? If a malicious user can submit
his own form and you are looking for a POST variable, how can you
ensure that $admin came from your form and not that user's? And if that
same user can hijack a session, that makes it so you have even less
precautions you can take.
I'm honestly interested in this. I've read the security section of the manual,
read similar threads and each time, I've come to the conclusion that you
can really only ever be so secure. And that all of the tests, checks,
balances you may implement are all for naught where a really determined
malicious user is concerned.
