Picklescan是美国Matthieu Maitre个人开发者的一款扫描Pickle文件安全风险的静态分析工具。 Matthieu Maitre Picklescan 0.0.33之前版本存在反序列化注入漏洞，该漏洞源于无法检测使用numpy.f2py.crackfortran.param_eval函数的恶意pickle文件，导致攻击者绕过安全检查，远程攻击者可在pickle文件中嵌入未检测到的代码，该代码在反序列化期间执行，从而实现加载不可信pickle数据的应用程序中的任意代码执行。

Vulnerability Title
picklescan - Undetected Remote Code Execution via numpy.f2py.crackfortran.param_eval
Source: CVE Program / CVE List V5
Vulnerability Description
picklescan before 0.0.33 fails to detect malicious pickle files using numpy.f2py.crackfortran.param_eval function in reduce methods, allowing attackers to bypass security checks. Remote attackers can embed undetected code in pickle files that executes during deserialization, enabling arbitrary code execution in applications loading untrusted pickle data.
