Bounty: $200$10000

Synopsis is our main web site. It is our most intricate application with a number of user inputs and access methods. is built on Ruby on Rails and leverages a number of Open Source technologies.

Rewards range from $200 up to $10000 and are determined at our discretion based on a number of factors. For example, if you find a reflected XSS that is only possible in Opera, and Opera is <2% of our traffic, then the severity and reward will be lower. But a persistent XSS that works in Chrome, at >60% of our traffic, will earn a much larger reward.
