What is CVE-2025-71344?

The Picklescan tool versions prior to 0.0.30 contain a vulnerability that allows malicious actors to execute arbitrary code. This issue arises from the inability of Picklescan to identify the built-in function ensurepip._run_pip when scanning for pickle files. Attackers can craft pickle files that include calls to ensurepip._run_pip within reduce methods, leading to successful remote code execution when the compromised pickle files are processed with the pickle.load() invocation. This flaw poses significant risks to systems relying on Picklescan for file scanning and should be addressed immediately.

Affected Version(s)

picklescan 0 < 0.0.30
