Is this vulnerability remotely exploitable?

Yes, indirectly. Any remote caller that can trigger OpenFGA Check calls through an application may be able to benefit from incorrect authorization decisions, provided the model and tuples meet the specific conditions.

What level of access does an attacker need?

An attacker generally needs either: - The ability to influence tuples (e.g., through self-service sharing or object creation flows), or - Access to an application that already uses a vulnerable model and data configuration. They do not need direct access to the OpenFGA server if they can interact via the application's normal APIs.

What is the safest general fix pattern?

The safest pattern is to adjust authorization models so that a single relation is not simultaneously driven by type-bound public and non-public access in conflicting ways, and to simplify relations so their access semantics are unambiguous.
