How do you protect against XSRF in Grails?

Question

How does one protect against XSRF attacks in Grails. I see that forms support the notion of useToken which (I think should suffice). However, remoteForm or other AJAX related request don't support this feature.

Also, is there a way to invert the functionality of useToken so that it is always used rather than enabled on a case by case basis?

Answer 1

You could try looking at the source code of the <g:form> tag. It uses a SynchronizerToken to create a token and store it in the session. Based on the resolution of this issue it should be possible to use the same token for all forms on the same page. I did not try this, but theoretically you would just need to manually create a hidden field on the form and generate the token in that field.
