Is this vulnerability remotely exploitable?

Yes. Any party that can obtain a valid access token from the affected Keycloak realm for another client application can attempt to use that token against the vulnerable Parse Server instance over the network.

What level of access is required to exploit this issue?

The attacker must be able to authenticate to the same Keycloak realm and acquire a legitimate access token for a different client application. This might be possible with a regular user account or a compromised client application within that realm.

What is the safest general fix pattern for this vulnerability?

Implement strict token claim validation: verify that the `azp` (or equivalent client-identifying claim) in incoming tokens matches the Parse Server's configured client ID and reject any tokens not explicitly issued for that client.
