Vulnerability from github – Published: 2026-07-04 03:31 – Updated: 2026-07-04 03:31

Details

picklescan before 0.0.30 fails to detect malicious pickle files using idlelib.run.Executive.runcode in reduce methods. Attackers can embed undetected code in pickle files that executes during pickle.load, enabling remote code execution in PyTorch models and supply chain attacks.

Severity ?
