CVE-2025-1944 Information

Description

picklescan before 0.0.23 is vulnerable to a ZIP archive manipulation attack that causes it to crash when attempting to extract and scan PyTorch model archives. By modifying the filename in the ZIP header while keeping the original filename in the directory listing an attacker can make PickleScan raise a BadZipFile error. However PyTorch’s more forgiving ZIP implementation still allows the model to be loaded enabling malicious payloads to bypass detection.
