libcgi-untaint-perl - 1.26-8 main

Dealing with large web based applications with multiple forms is a
minefield. It's often hard enough to ensure you validate all your
input at all, without having to worry about doing it in a consistent
manner. If any of the validation rules change, you often have to alter
them in many different places. And, if you want to operate taint-safe,
then you're just adding even more headaches.
.
CGI::Untaint provides a simple, convenient, abstracted and extensible
manner for validating and untainting the input from web forms.
.
You simply create a handler with a hash of your parameters (usually
$q->Vars), and then iterate over the fields you wish to extract,
performing whatever validations you choose. The resulting variable is
guaranteed not only to be valid, but also untainted.
