Upgrade picklescan to version 0.0.23 or higher.
Overview
picklescan is a Security scanner detecting Python Pickle files performing suspicious actions
Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity when PickleScan attempts to extract and scan PyTorch model archives, an attacker can manipulate the ZIP file by modifying the filename in the ZIP header while retaining the original filename in the directory listing. This causes PickleScan to raise a BadZipFile error, preventing proper scanning, while PyTorch's more lenient ZIP handling still allows the model to load, enabling malicious payloads to bypass detection.
