Summary: rpc.py vulnerable to Deserialization of Untrusted Data

Details: rpc.py through 0.6.0 allows Remote Code Execution because an unpickle occurs when the "serializer: pickle" HTTP header is sent. In other words, although JSON (not Pickle) is the default data format, an unauthenticated client can cause the data to be processed with unpickle. [Per the maintainer](https://github.com/abersheeran/rpc.py/issues/22), rpc.py is not designed for an API that is open to the outside world, and external requests cannot reach rpc.py in real world use. A [fix](https://github.com/abersheeran/rpc.py/commit/491e7a841ed9a754796d6ab047a9fb16e23bf8bd) exists on the `master` branch. As a workaround, use the following code to turn off pickle in older versions: ``` del SERIALIZER_NAMES[PickleSerializer.name] del SERIALIZER_TYPES[PickleSerializer.content_type]
