OpenFGA is a high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar. OpenFGA v1.8.10 to v1.3.6 (Helm chart <= openfga-0.2.28, docker <= v.1.8.10) are vulnerable to authorization bypass when certain Check and ListObject calls are executed. This issue has been patched in version 1.8.11.

GHSA-w222-m46c-mgh6 — OpenFGA Authorization Bypass

Affected: Go: github.com/openfga/openfga

Overview OpenFGA v1.8.10 or previous (Helm chart <= openfga-0.2.28, docker <= v.1.8.10) are vulnerable to authorization bypass when certain Check and ListObject calls are executed.

Am I Affected? If you are using OpenFGA v1.8.10 or previous, specifically under the following conditions, you are affected by this authorization bypass vulnerability: - Calling Check API or ListObjects with an [authorization model](https://openfga.dev/docs/concepts#what-is-an-authorization-model) that has tuple cycle. - [Check query cache](https://github.com/openfga/openfga/blob/9b5974458b777707ed2a30ba6303699499e655ee/.config-schema.json#L528) is enabled, and - There are multiple check / list objects requests involving the tuple cycle within the check query TTL

Fix Upgrade to v1.8.11. This upgrade is backwards compatible.
