What is CVE-2025-71340?

The vulnerability in picklescan prior to version 0.0.30 allows attackers to exploit undetected malicious pickle files. These files can invoke the idlelib.pyshell.ModifiedInterpreter.runcode in reduce methods, leading to arbitrary command execution upon loading via pickle.load(). This poses a significant risk as it may enable supply chain attacks on PyTorch models and other saved Python objects. Users are advised to update to version 0.0.30 or later to mitigate this risk.

Affected Version(s)

picklescan 0 <= 0.0.26

picklescan 0.0.30
