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.
