mscott has an XSS vunerability mod at http://www.expertzzz.com/Downloadz/view/3080 and is also available on his www.makeasocialnetwork.com site.

Good to know too that the new Dolphin 6.1 passed Hacker Safe status. In order to meet Hacker Safe status you have to pass a series of tests.

Hacker safe does daily diagnostics of your site and possible vulnerabilities. I've worked on a few sites that use their service and it comes with a control panel that gives you suggestions on how to prevent any see more problems.
