Comment 2 Doran Moppert 2020-12-18 01:27:38 UTC

Statement:

Both jsonpickle and pickle are documented as being able to execute arbitrary code when loading pickles, and intended for use only with trusted data. This is expected behaviour, as clearly indicated in the jsonpickle README and at https://docs.python.org/3/library/pickle.html
