      "value": "OpenFGA, an authorization/permission engine, is vulnerable to a denial of service attack in versions prior to 1.4.3. In some scenarios that depend on the model and tuples used, a call to `ListObjects` may not  release memory properly. So when a sufficiently high number of those calls are executed, the OpenFGA server can create an `out of memory` error and terminate. Version 1.4.3 contains a patch for this issue."

En algunos escenarios que dependen del modelo y las tuplas utilizadas, es posible que una llamada a `ListObjects` no libere memoria correctamente. Entonces, cuando se ejecuta una cantidad suficientemente alta de esas llamadas, el servidor OpenFGA puede crear un error de \"memoria insuficiente\" y finalizar. La versi\u00f3n 1.4.3 contiene un parche para este problema."
