Forget Sidejacking, Clickjacking, and Carjacking: Enter Formjacking

Formjacking, found by Jerry Hoff while testing AntiSamy. An injected self-closing <form/> tag makes FF3 and IE7 ignore the real <form> that follows, so every input on the page submits to the attacker. AntiSamy's tag balancing turned the attacker's unclosed opening tag into the self-closed form that triggers it, alongside the same quirk for <b/> and <i/>.
