You should ask it to perform a security analysis of its code. That program is not safe to run on untrusted input. I am curious to know whether it can find the issue itself with no specific prompting beyond generally reviewing for security issues. Though that it generates dangerous code in the first place is a good reason to be very wary of running code from ChatGPT.

ChatGPT codes at a novice level so while it may get a task done, it produces throwaway code that shouldn't generally be learned from or considered suitable for "serious" code (whatever that might mean). Among other oddities,

my $mod_time = (stat($file_path))[9];
my $date = strftime "%Y_%m_%d", localtime($mod_time);
my ($year, $month, $day) = split('_', $date);
# ...
$new_file_name = "${year}_${month}_${day}_$count.jpg";

Of course, pointing this out won't help ChatGPT become a better programmer so it is not uncommon for people to provide responses and reviews of generated code which are less helpful or more actively hostile than they would otherwise be.
