CVE-2025-71355

Picklescan before 0.0.25 fails to detect unsafe global functions in the Numpy library, allowing attackers to bypass static analysis and execute arbitrary code during deserialization. Attackers can craft malicious pickle files using numpy.testing._private.utils.runstring within the reduce method to import dangerous libraries like os and execute arbitrary OS commands when the pickle file is loaded.

Summary		(es) Picklescan anterior a la versión 0.0.25 no logra detectar funciones globales inseguras en la biblioteca Numpy, lo que permite a los atacantes eludir el análisis estático y ejecutar código arbitrario durante la deserialización. Los atacantes pueden crear archivos pickle maliciosos utilizando numpy.testing._private.utils.runstring dentro del método reduce para importar bibliotecas peligrosas como os y ejecutar comandos arbitrarios del sistema operativo cuando se carga el archivo pickle.
