NAME

Catalyst::Plugin::HTML::Scrubber - Catalyst plugin for scrubbing/sanitizing incoming parameters

SYNOPSIS

 use Catalyst qw[HTML::Scrubber];

 MyApp->config( 
     scrubber => {
         auto => 1,  # automatically run on request
         ignore_params => [ qr/_html$/, 'article_body' ],
         
         # The following are options to HTML::Scrubber
         params => [
             default => 0,
             comment => 0,
             script => 0,
             process => 0,
             allow => [qw [ br hr b a h1]],
         ],
     },
);

DESCRIPTION

On request, sanitize HTML tags in all params (with the ability to exempt some if needed), to protect against XSS (cross-site scripting) attacks and other unwanted things.

EXTENDED METHODS

setup

See SYNOPSIS for how to configure the plugin, both with its own configuration (e.g. whether to automatically run, whether to exempt certain fields) and passing on any options from HTML::Scrubber to control exactly what scrubbing happens.

dispatch

Sanitize HTML tags in all parameters (unless `ignore_params` exempts them) - this includes normal POST params, and serialised data (e.g. a POSTed JSON body) accessed via `$c->req->body_data` or `$c->req->data`.

SEE ALSO

Catalyst, HTML::Scrubber.
