Descriptions

Envoy is a cloud-native, open source edge and service proxy. Due to how Envoy invoked the nlohmann JSON library, the library could throw an uncaught exception from downstream data if incomplete UTF-8 strings were serialized. The uncaught exception would cause Envoy to crash.

Envoy es un proxy de servicio y borde de código abierto, nativo de la nube. Debido a cómo Envoy invocó la librería JSON de nlohmann, la librería podría generar una excepción no detectada de los datos posteriores si se serializaran cadenas UTF-8 incompletas. La excepción no detectada provocaría que Envoy fallara.
