Insecure Global Handling in Picklescan Affects Python Package Security

CVE-2025-1716

Summary

Picklescan versions earlier than 0.0.21 have a critical security flaw where the 'pip' command is not treated as an unsafe global. An attacker can exploit this vulnerability by crafting a malicious model that utilizes Pickle, enabling it to pull in harmful packages from external sources like PyPI or GitHub through pip.main(). This oversight allows the model to pass security checks during scanning, falsely appearing secure while potentially executing harmful operations.
