Discussion: I have started with Breaking bank, i think the key is to forge the Authorization header, i found this in the source code:
// TODO: is this secure enough?
        if (!jku.startsWith('http://127.0.0.1:1337/')) {
            throw new Error('Invalid token: jku claim does not start with http://127.0.0.1:1337/');
        }
I am sure this is the intended way but i cannot seem to get the SSRF to work i keep getting an annoying "Invalid signature" error.

there is an open redirect that you can exploit and use your own public key to validate the jwt token
