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."},{"lang":"es","value":"OpenFGA, un motor de autorización/permisos, es vulnerable a un ataque de denegación de servicio en versiones anteriores a la 1.4.3.
