The intent of this xssmas challenge is to find an XSS vector that triggers in as many contexts as possible and is inspired by Gareth Heyes's classic "One vector to rule them all". Rules XSS this page. Your injection will be reflected in a lot of different contexts. Escape all of them to get as many alerts popping as possible. Make that XSS vector short. Submit our solution in an email. Tip: Just call alert() and we'll count for you. Winner is the submission with the most contexts successfully XSS'd, ranked by size (shorter is better).
