Is this vulnerability remotely exploitable?

Yes. Any attacker who can reach the Parse Server's OAuth2 authentication endpoints and who possesses a valid OAuth2 token from the same provider can attempt to exploit this issue.

Does exploitation require special privileges or a specific user role?

No special application privileges are required. The attacker only needs a valid OAuth2 token issued by the same identity provider used by the vulnerable Parse Server instance.

What is the safest general fix pattern for this issue?

The most robust fix is to enforce strong token-to-user binding by configuring the OAuth2 adapter with an explicit `useridField` (or equivalent) and verifying that the token's user identifier matches the Parse user being authenticated, alongside standard token validation checks (issuer, audience, expiry).
