Picklescan is missing detection when calling built-in python ensurepip._run_pip

SummaryUsing ensurepip.runpip function, which is a built-in python library function to execute remote pickle file. DetailsThe attack payload executes in the following steps:First, the attacker craft the payload by calling to ensurepip.runpip function in reduce methodThen when the victim after...

Deserialization of Untrusted Data

Overview picklescan is a Security scanner detecting Python Pickle files performing suspicious actions Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the ensurepip.runpip function. An attacker can execute arbitrary code by crafting malicious pickle files...

CVE-2025-71344

picklescan before 0.0.30 affected versions 0.0.26 and earlier fails to detect the ensurepip.runpip built-in function when scanning pickle files, allowing attackers to execute arbitrary code. Malicious pickle files embedding ensurepip.runpip calls in reduce methods bypass picklescan detection and...
