This cross-site scripting (XSS) cheat sheet contains many vectors that can help you bypass WAFs and filters. You can select vectors by the event, tag or browser and a proof of concept is included for every vector. You can download a PDF version of the XSS cheat sheet. This cheat sheet was brought to by PortSwigger Research. XSS filter evasion refers to a variety of methods used by attackers to bypass XSS (Cross-Site Scripting) filters. There are many ways to inject malicious JavaScript into web page code executed by the client, and with modern browsers, attackers must not only exploit an application vulnerability but also evade any input validation performed by the application and server, and fool complex browser.

For a cheatsheet on the attack vectors related to XSS, please refer to the XSS Filter Evasion Cheat Sheet. More background on browser security and the various browsers can be found in the Browser Security Handbook. Before reading this cheatsheet, it is important to have a fundamental understanding of Injection Theory.

The Book takes care to explain the elevation of Cross-Site Scripting (XSS) to the title of HTML Injection. This quick reference describes some of the common techniques used to inject a payload into a web application.

In the examples below the biohazard symbol (U+2623), ☣, represents an executable JavaScript payload. It could be anything from a while loop to lock the browser, e.g. while(1){a=1;}, or something more useful that a creative attacker comes up with. You can quite easily find “XSS Cheat Sheets” elsewhere. The intent of this reference is to instill a sense of methodology into finding HTML injection vulnerabilities. Good exploits take advantage of HTML syntax and browser quirks in creative ways. Take the time to experiment with simple payloads and observe how (and where) the web application reflects them. Then turn towards the list of complex attacks on a cheat sheet.

Also notice how the syntax of elements and JavaScript have been preserved in cases where single- or double-quotes are used to prefix a payload. The injected quote prematurely ends a quoted string, which means there will be a dangling quote at the end. Whether the reflection point is in an intrinsic event or a JavaScript block, the dangling quote is trivially consumed by throwing an extra variable definition with an open quote:

Parallels app for mac. ;a='

The dangling quote will close the delimiter and, in most cases, the syntax will be preserved. This type of closure isn’t really necessary for an exploit to work, but it’s a sign craftier exploits.
