Motivation
This change hardens Java deserialization operations against attack. Even a simple operation like an object deserialization is an opportunity to yield control of your system to an attacker. In fact, without specific, non-default protections, any object deserialization call can lead to arbitrary code execution.
Modifications
I have added pixee java security toolkit as a dependency, and in pulsar functions in the the Serialization/ Deserialization file I have added
ObjectInputFilters.enableObjectFilterIfUnprotected
to the object input stream.Motivation
