The rapidjson parser uses a recursive parsing method by default. If the input json has a large depth of recursive structure, the parser function may run into stack overflow.\n\nAffected Scenarios:\nUse bRPC server with protobuf message to serve http+json requests from untrusted network. Or directly use\u00a0JsonToProtoMessage to convert json from\u00a0untrusted input.\n\n\n\nHow to Fix: \n(Choose one of the following options)\u00a0\n1. Upgrade bRPC to version 1.15.0, which fixes this issue.\n2. Apply this patch: https://github.com/apache/brpc/pull/3099 \n\n\n\nNote:\nNo matter which option \n\nyou choose, you should know that the fix introduces a recursion depth limit with default value 100. It affects these functions:\u00a0\n\nProtoMessageToJson, ProtoMessageToProtoJson, JsonToProtoMessage, and ProtoJsonToProtoMessage.\n\n If your requests contain json or protobuf messages that have a depth exceeding the limit, the request will be failed after applying the fix. You can modify the gflag json2pb_max_recursion_depth to change the limit."}, {"lang": "es", "value": "La recursi\u00f3n incontrolada en el componente json2pb de Apache bRPC (versi\u00f3n < 1.15.0) en todas las plataformas permite a atacantes remotos colapsar el servidor enviando datos JSON recursivos profundos.\n\nCausa Ra\u00edz:\nEl componente bRPC json2pb utiliza rapidjson para analizar datos JSON de la red. El analizador de rapidjson utiliza un m\u00e9todo de an\u00e1lisis recursivo por defecto. Si el JSON de entrada tiene una gran profundidad de estructura recursiva, la funci\u00f3n del analizador puede sufrir un desbordamiento de pila.\n\nEscenarios Afectados:\nUsar el servidor bRPC con mensajes protobuf para atender solicitudes HTTP+JSON de una red no confiable. O usar directamente JsonToProtoMessage para convertir JSON de entrada no confiable.\n\nC\u00f3mo Solucionar:\n(Elija una de las siguientes opciones)\n1.
