Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

picklescan picklescan是picklescan公司的一款Python反序列化漏洞扫描工具。 picklescan 1.0.4之前版本存在输入验证错误漏洞，该漏洞源于未能阻止至少七个Python标准库模块（包括uuid、_osx_support、_aix_support、_pyrepl.pager和imaplib），暴露了八个可直接进行任意命令执行的函数，可能导致攻击者通过构造恶意pickle文件导入这些未阻止的模块实现远程代码执行，完全绕过picklescan的安全验证。

Vulnerability Title
picklescan - Remote Code Execution via Unblocked Standard Library Modules
Source: CVE Program / CVE List V5
Vulnerability Description
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.
