Insecure deserialization in Wire

Details

As written in the advisory (Markdown source, shown as plain text).

Due to how Wire handles type information in its serialization format, malicious payloads can be passed to a deserializer. e.g. using a surrogate on the sender end, an attacker can pass information about a different type for the receiving end. And by doing so allowing the serializer to create any type on the deserializing end. **This is the same issue that exists for .NET BinaryFormatter https://docs.microsoft.com/en-us/visualstudio/code-quality/ca2300?view=vs-2019** This also applies to the fork of Wire, AkkaDotNet/Hyperion.
