[TYPO3-mvc] Can forms be easily manipulated?

[Jan Kornblum]

Hi Chris,

thanks a lot. Yes, i think i've read about something like this (also 
regarding the encryption key is used for generating the hash) anywhere 
but i was not sure any more.

Despite: If there is a trusted form containing a property "pid", this 
pid might be modified and extra work would be neccessary to make it 
safe. Correct?

Kind regards, Jan
