Cron security issues?

Does the use of cron (HP-UX 11) present a security risk IF it is only given to accounts which have shell access anyway.

If it does present a risk, what is the risk?

Can a script (or command) run via cron; run anything, write anywhere or read anywhere that the same user can not do outside of cron?
