Web security, are there issues with hidden fields (no sensitive data)?

Question

I was having a discussion with coworkers. We have to implement some security standards. We know not to store \'sensitive, addresses, date of birth\' information in hidden

Answer 1

It's only a security hole if you're exposing information that wouldn't be otherwise available to the end user and/or aren't validating it on return.

I'd look instead to storing said information in a server side session variable instead...
