Here you find my custom XSS and CSRF cheat sheet. I know that there are running good cheat sheets out there, but since some of them are offline from time to time, I decided to create a little collection of useful XSS stuff. I added some stuff from other well known cheat sheets (e.g. from http://ha.ckers.org/xss.html), please scroll down to see a complete list of sources. There

Today, I am sorting out some js files and added markdown support to the People's Network in May. However, the freedom of UGC means we need to take some measures to maintain it, such as anti-XSS attacks. I wrote an email in early September. The background at that time was that the markdown support was available on the same day, and it seemed that it was not right at night. As a result, XSS attacks began to b
