Is this vulnerability remotely exploitable?

Yes. If OliveTin is accessible over the network and uses JWT authentication, a remote attacker who can obtain validly signed JWTs (for any audience under the same issuer/key) may be able to authenticate to OliveTin without possessing a token specifically issued for it.

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

The attacker needs access to a valid, correctly signed JWT from the same identity provider or signing key that OliveTin trusts. This could come from another application that uses the same issuer/key, from compromised client secrets, or from any environment where tokens for a different audience are obtainable.

What is the safest general fix pattern?

Enforce strict JWT validation that includes: - Checking that the `aud` claim matches a configured, OliveTin-specific value. - Verifying the issuer, expiration, and any other relevant claims. Additionally, use distinct audiences and keys per service so that tokens are not reusable across applications.
