Vulnerability Title
picklescan - Arbitrary Code Execution via Undetected ensurepip._run_pip Function
Source: CVE Program / CVE List V5
Vulnerability 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.
