You're correct.

Maybe either Mojolicious::Plugin::CSRFProtect or Mojolicious::Plugin::CSRFDefender would be reasonable steps in the right direction. The former looks to be more thorough, while the latter looks a little more foolproof.

Mojolicious::Plugin::CSRFProtect adds a hidden input field to forms, adds a token to ajax requests, rejects all non-GET/HEAD requests without the token, and simplifies the safeguarding of GET/HEAD requests and side-effect links.

This seems to provide the mechanism needed to implement one of the prevention measures mentioned in the Wikipedia article to which you linked: "Requiring a secret, user-specific token in all form submissions and side-effect URLs prevents CSRF; the attacker's site cannot put the right token in its submissions."

I'm using Mojolicious::Plugin::CSRFProtect in a project. It's convenient. All I have to do is make sure my routes for forms only respond to POST requests, and that my forms use the "form_for" helper. pretty slick.
