Secure perl forum board software

[Anton Karpov]

Since almost every php-based board engine is just a piece of crap, as the
php itself, I'm looking for good perl based board software. The _most_
important point is security, noone except authorised users should be able to
get forum data. I've looked at SMF, phpBB, but it's all php based and
googling gor 'foobar vulnerability' (where 'foobar' is SMF or phpBB etc..)
shows tons of vulns.
Can someone recommend something suitable?
Thanks.
