picklescan – Arbitrary Code Execution via Undetected ensurepip._run_pip Function_CVE-2025-71344

{
    "lastseen": "",
    "description": "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.",
