An anonymous reader writes "Bloggers have been buzzing about the new wave of "Web 2.0" campaign sites, but it seems that a lot of presidential candidates haven't bothered to protect themselves from cross-site scripting attacks.

Some of the holes are low-risk, but others would allow a user's accounts on the affected website to be compromised. A victim would simply have to click on a maliciously crafted link that appears to lead to the candidate's site."
