Quick fix

PYSEC-2026-247 — picklescan: upgrade to the fixed version with the command below.

pip install --upgrade 'picklescan>=0.0.30'

Details

picklescan before 0.0.30 fails to detect cProfile.runctx function calls in pickle file reduce methods, allowing attackers to execute arbitrary code. Malicious pickle files bypass picklescan detection and execute remote code when loaded via pickle.load().
