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 due to improper handling of modified ZIP file flag bits. Attackers can exploit this by altering specific bits in the ZIP file headers within PyTorch model archives, embedding malicious pickle files that remain undetected by PickleScan while still being successfully loaded by PyTorch's torch.load().
