  "details" : [ "OpenFGA is an authorization/permission engine built for developers. In versions 0.1.4 through 1.13.1, 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. Only those who run OpenFGA with `--authn-method` preshared, with the playground enabled, and with the playground endpoint accessible beyond localhost or trusted networks are vulnerable. To remediate the issue, users should upgrade to OpenFGA v1.14.0, or disable the playground by running `./openfga run --playground-enabled=false.`", "A flaw was found in OpenFGA, an authorization/permission engine. When OpenFGA is configured to use preshared-key authentication and the built-in playground is enabled and accessible beyond localhost or trusted networks, a remote attacker can exploit this vulnerability. The local server includes the preshared API key in the HTML response of the /playground endpoint, leading to information disclosure of the API key. This can allow unauthorized access to the system." ],
  "statement" : "This is an Important information disclosure flaw in OpenFGA, an authorization engine used in Red Hat products. The vulnerability occurs when OpenFGA is configured with preshared-key authentication and its built-in playground is enabled and exposed beyond localhost or trusted networks. The /playground endpoint, intended for development, can then reveal the preshared API key, potentially leading to unauthorized access.",
