OpenFGA is an authorization/permission engine built for developers.

Published Apr 17, 2026 · updated Aug 24, 2026 · openfga openfga

OpenFGA is an authorization/permission engine built for developers.

To remediate the issue, users should upgrade to OpenFGA v1.14.0, or disable the playground by running
