Fickling versions up to and including 0.1.6 do not treat Python’s runpy module as unsafe.

If a user relies on Fickling’s output to decide whether a pickle is safe to deserialize, this misclassification can lead them to execute attacker-controlled code on their system. This affects any workflow or product that uses Fickling as a security gate for pickle deserialization.
