CVE-2025-71344
Published:June 22, 2026
Updated:June 28, 2026
picklescan before 0.0.30 (affected versions 0.0.26 and earlier) fails to detect the ensurepip._run_pip built-in function when scanning pickle files, allowing attackers to execute arbitrary code. Malicious pickle files embedding ensurepip._run_pip calls in reduce methods bypass picklescan detection and achieve remote code execution upon pickle.load() invocation.
