Summary
OpenFGA: Unauthenticated playground endpoint discloses preshared API key in HTML response
Details

Description

When OpenFGA is configured to use preshared-key authentication with the built-in playground enabled, the local server includes the preshared API key in the HTML response of the /playground endpoint. The /playground endpoint is enabled by default and does not require authentication. It is intended for local development and debugging and is not designed to be exposed to production environments.

Am I Affected?

You are affected if you meet each of the following preconditions: * You are running OpenFGA with --authn-method preshared, and * The playground is enabled, and * The playground endpoint is accessible beyond localhost or trusted networks.

Fix

Upgrade to OpenFGA v1.14.0, or disable the playground by running ./openfga run --playground-enabled=false.

Severity
6.5 (Medium)
