Overview OpenFGA v1.8.4 or previous (Helm chart < openfga-0.2.22, docker < v.1.8.5) are vulnerable to authorization bypass when certain Check and ListObject calls are executed.
Am I Affected? If you are using OpenFGA v1.8.4 or previous, specifically under the following conditions, you are affected by this authorization bypass vulnerability:
- Calling Check API or ListObjects with a model that has a relation directly assignable to both public access AND userset with the same type, and
- A type bound public access tuple is assigned to an object, and
- userset tuple is not assigned to the same object, and
- Check request's user field is a userset that has the same type as the type bound public access tuple's user type
Fix Upgrade to v1.8.5. This upgrade is backwards compatible.

Limited exploitation activity has been observed. Close monitoring and planned remediation are recommended.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
