title: JSON vs. Pickle security
body: <p>I recently came across the security problems of the Python pickle and cPickle modules.
  Obviously, there are no real security measures implemented in pickle unless you overwrite
  the find_class method as a basic modification to get a bit more security. But I often
  heard that JSON is more secure.</p>
  
  <p>Can anyone elaborate a bit on this?`Why is JSON more secure than pickle?</p>
  
  <p>Thanks a lot!
  Mark</p>
