CVE-2026-56315 · picklescan - Remote Code Execution via Unblocked Standard Library Modules

This page contains facts from public vulnerability sources. Check the original advisory before updating.

picklescan before 1.0.4 fails to block at least seven Python standard library modules (including uuid, _osx_support, _aix_support, _pyrepl.pager, and imaplib) exposing eight functions that provide direct arbitrary command execution. Attackers can craft malicious pickle files importing these unblocked modules to achieve remote code execution while bypassing picklescan's safety validation entirely.
