XSS is one of the most popular vulnerabilities to hunt for. Is it the name radiating coolness? Is it the impact it can have? Is it because that popup is so rewarding? Who knows! All we know at Intigriti is that people LOVE XSS but that many have only scratched the surface of what XSS can be!

In this article, we’ll list all the XSS challenges we’ve hosted in the past, so you can keep on polishing those skills. Leave no XSS uncovered!

Note that some of these challenges may not involve XSS πŸ˜‰
