The risk is only for restricted or chrooted accounts being able to access files the account could never access before.

The risk is the same for a user with shell access, and the same user with access to commands/files via crontab. Ditto at and batch.

For any valid shell user, accessing crontab has a greater chance of screwing things up, because the environment in cron jobs is not the same as the interactive environment. This leads to errors and bad code trashing things.

So if security is set correctly, inept crontab users mostly trash their own stuff.

So, how do you want to define security?

partimaged-passwd(8)				       Partition Image Server Configuration				      partimaged-passwd(8)

NAME
partimaged-passwd - Manage partimaged user accounts SYNTAX
partimaged-passwd [-Dhl] username password partimaged-passwd [-Dhl] username DESCRIPTION
partimaged can either authenticate against local user accounts (This needs access to /etc/shadow. As this is a potential security risk this method is not recommended) or its own password database in /etc/partimaged/passwd.db. To simplify the management of the partimaged user database this tool was written. It allows to easily add and remove users or list the users in the database. All users in this database are allowed to access the partimaged server. OPTIONS
-D username Delete the specified user from the password file. -l List users in password file and exit. -h Output help information and exit. FILES
/etc/partimaged/passwd.db AUTHORS
