Last modified

CVE-2025-71340 is a high-severity vulnerability rated 7.6/10 on the CVSS scale. picklescan through 0.0.26 fails to detect malicious pickle files that invoke idlelib.pyshell.ModifiedInterpreter.runcode in __reduce__ methods. Attackers can embed undetected code in pickle files that executes arbitrary commands when the file is loaded via pickle.load(), enabling supply chain attacks on PyTorch models and saved Python objects. EPSS estimates a 0.30% chance of exploitation in the next 30 days.
