Google: >> Protobuf >> 4.23.1 Security Vulnerabilities
A denial-of-service (DoS) vulnerability exists in google.protobuf.json_format.ParseDict() in Python, where the max_recursion_depth limit can be bypassed when parsing nested google.protobuf.Any messages.
Due to missing recursion depth accounting inside the internal Any-handling logic, an attacker can supply deeply nested Any structures that bypass the intended recursion limit, eventually exhausting Python’s recursion stack and causing a RecursionError.

The JsonToBinaryStream() function is part of the protocol buffers C++ implementation and is used to parse JSON from a stream. If the input is broken up into separate chunks in a certain way, the parser will attempt to read bytes from a chunk that has already been freed.
