Summary Duplicate Advisory: Picklescan missing detection when calling built-in python library function timeit.timeit() ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-v7x6-rv5q-mhwc. This link is maintained to preserve external references. ### Original Description 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.
