Vulnerability Report
Generated by CyberWatcher
Description
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.
