CVE-2025-71351: Picklescan

High severity, CVSS 7.6. EPSS: 0.6% chance of exploitation in the next 30 days.

picklescan before 0.0.25 fails to detect malicious pickle files that use timeit.timeit() in the __reduce__ method, allowing remote code execution. Attackers can craft pickle files that import dangerous libraries like os and execute arbitrary system commands, which evade picklescan detection and execute when pickle.load() is called.
