What potential security risks are associated with running cron jobs on a server?

Potential security risks associated with running cron jobs on a server include the possibility of sensitive information being exposed, unauthorized access to the server, and the execution of malicious code. To mitigate these risks, it is important to ensure that cron jobs are properly configured with limited permissions and access to only necessary resources.

// Example of setting permissions for a cron job in PHP
chmod('/path/to/cron_job.php', 0700);
