TypeNameHandling and security

TypeNameHandling sounds like a potential security-hole if it allows instantiation of arbitrary types from untrusted JSON.

Is it possible to supply a type white-list so only types from that list may be constructed? Or is there a build in mechanism that makes this save that I'm missing?

No. The JSON property is only used if TypeNameHandling is enabled so if you're worried about it then you can safely not turn it on.
