Is this vulnerability remotely exploitable?

Yes. Anyone with a valid Traccar account who can reach the affected OIDC/OAuth endpoints can attempt to exploit the issue by crafting authorization requests with malicious `redirect_uri` values. Remote exploitation typically involves luring victims into following specially crafted authentication links or initiating SSO flows.

Does an attacker need valid credentials to exploit this?

The description indicates that exploitation requires an authenticated user, so having a valid Traccar account is a prerequisite. However, the actual misuse may target other users' accounts on OAuth-integrated applications by tricking them into completing poisoned authorization flows.

What is the safest general fix pattern?

The safest approach is to implement strict redirect URI validation: - Maintain a server-side list of exact redirect URIs registered per OAuth client. - Reject any authorization request whose `redirect_uri` does not exactly match a registered value. - Avoid allowing arbitrary external URLs or wildcard patterns in redirect URIs.
