Do you mean CSRF? I don't see upvote links for some reason so I can't debug - but does auth contains a CSRF token? If not you could craft a page which upvote posts for the current visitor (if they're logged in HN) You could mitigate it with server side checks (or maybe some new browser tech I don't know about?) but I think the synchroniser token pattern is still the current solution.
