What is CVE-2025-1945?

PickleScan versions prior to 0.0.23 are susceptible to an issue where it fails to properly detect malicious pickle files embedded within PyTorch model archives. Attackers can exploit this vulnerability by manipulating ZIP file header bits to include harmful pickle files that evade detection by PickleScan. When these compromised models are loaded using PyTorch's torch.load() function, it can result in the execution of arbitrary code, posing a significant security risk.

Affected Version(s)

picklescan 0.0.1 < 0.0.23
