Summary
Duplicate Advisory : Picklescan is missing detection when calling built-in python idlelib.pyshell.ModifiedInterpreter.runcode
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-3gf5-cxq9-w223. This link is maintained to preserve external references.

Original Description

picklescan through 0.0.26 fails to detect malicious pickle files that invoke idlelib.pyshell.ModifiedInterpreter.runcode in reduce methods. Attackers can embed undetected code in pickle files that executes arbitrary commands when the file is loaded via pickle.load(), enabling supply chain attacks on PyTorch models and saved Python objects. This is fixed in version 0.0.30.
