CVE-2022-35411 Information

Description

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.
