welcome to W.W.
Asking www.google.com for 'perl security' gives out this link, which should be a good start:
[search.cpan.org...]
Perl security: An introduction to security issues for writing and deploying Perl programs.
Another google search 'perl security "sql injection"'
leads to
[stonehenge.com...]
which looks promising.
