CVE-2025-71372: Picklescan detection bypass via numpy getlincoef gadget

CVE-2025-71372 · Severity: high · CVSS 8.1 · Published 2026-07-04

Picklescan is a security tool used to scan Python pickle files and AI models for malicious code before they are opened. A vulnerability in this tool allows specially crafted malicious files to bypass its safety checks by using a specific hidden command. If a user relies on Picklescan to vet a file and then opens it, an attacker could gain full control over the user's system, potentially leading to data theft or supply-chain attacks.

Technologies: picklescan (PyPI). Vendors: PyPI.

Technical details

Picklescan is vulnerable to a deserialization bypass (CWE-502) because its blocklist/heuristic engine fails to identify the 'numpy.f2py.crackfortran.getlincoef' function as a dangerous gadget. An attacker can craft a malicious pickle file that utilizes this function within a '__reduce__' method to execute arbitrary Python code. When a victim scans the file, Picklescan incorrectly flags it as safe; subsequent loading of the file via 'pickle.load()' triggers the exploit. This vulnerability requires the victim to attempt to load the malicious file (User Interaction) and is resolved in version 0.0.33.
