Is this vulnerability remotely exploitable?

Yes. If an attacker can obtain or generate a valid user JWT, they can attempt to use it directly against the RAG API over the network, without needing local access to the server.

What level of access does an attacker need to exploit this?

They need access to a valid user token or the ability to sign tokens with the shared secret. This could arise from compromised user accounts, token theft, or other application-layer issues that expose JWTs.

What is the safest general fix pattern?

Separate authentication concerns by using distinct JWT secrets or key pairs for each logical service, and strictly verify token audience, issuer, and scopes on the RAG API so only appropriately scoped tokens are accepted.
