Quick fix

PYSEC-2026-245 — picklescan: upgrade to the fixed version with the command below.

pip install --upgrade 'picklescan>=0.0.28'

Details

picklescan before 0.0.28 fails to detect malicious pickle files that invoke torch.utils._config_module.load_config function within reduce methods. Attackers can craft pickle files embedding arbitrary code that evades detection but executes during pickle.load, enabling remote code execution in supply chain attacks.
