> how do I figure out if the code that throws these warnings is really vulnerable, how do I fix code that is?

warnings will show you a line number, if you are only expecting a scalar to be returned use scalar like Corion showed.

But if you really expect multi values from http for the same element you should look into CGI for recommended workaround.¹

HTH! :)

¹) you can disable this warning by setting $CGI::LIST_CONTEXT_WARN to 0 or by using the multi_param() method instead
