Solution:

This was the most easiest challenge in the CTF. Intercept a request and take a look at the cookie. Base64 decode the cookie and we will get {"admin":0}. We can change the admin's value to 1 to make the user admin. We can base64 encode this new JSON and send that as the cookie to get the flag. Final Payload - eyJhZG1pbiI6MX0= ( Base64 decoded - {"admin":1} ).
