I'd like to suggest that the title be changed into "Origin-based CORS bypass", to make it more professional

Also, this addition should be below the HTML snippet. Otherwise the document doesn't make sense

1. `Origin:null`
2. `Origin:attacker.com`
3. `Origin:attacker.target.com`
4. `Origin:attackertarget.com`
5. `Origin:sub.attackertarget.com`
6. `Origin:attacker.com and then change the method Get to post/Post to Get`
7. `Origin:sub.attacker target.com`
8. `Origin:sub.attacker%target.com`
9. `Origin:attacker.com/target.com`

```
