This game will help you improve your
Cross-Site Scripting (
XSS) skills through challenges. Each challenge is made up of a template, function, value, and a number of filters. Filters are mitigations based on real-world examples and are generated dynamically. It is up to you to find a payload that bypasses all filters so it executes the function with the expected argument. In case you are not familiar with
XSS vulnerabilities yet,
check out this video to get you up to speed. Good luck!
