OpenFGA Improper Policy Enforcement
OpenFGA is a high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar. OpenFGA v1.4.0 to v1.11.0 ( openfga-0.1.34 <= Helm chart <= openfga-0.2.48, v.1.4.0 <= docker <= v.1.11.0) are vulnerable to improper policy enforcement when certain Check and ListObject calls are executed. This issue has been patched in version 1.11.1.
