CVE-2025-71344

picklescan before 0.0.30 (affected versions 0.0.26 and earlier) fails to detect the ensurepip._run_pip built-in function when scanning pickle files, allowing attackers to execute arbitrary code. Malicious pickle files embedding ensurepip._run_pip calls in __reduce__ methods bypass picklescan detection and achieve remote code execution upon pickle.load() invocation.

Summary		(es) picklescan antes de la versión 0.0.30 (versiones afectadas 0.0.26 y anteriores) no detecta la función incorporada ensurepip._run_pip al escanear archivos pickle, permitiendo a los atacantes ejecutar código arbitrario. Los archivos pickle maliciosos que incrustan llamadas a ensurepip._run_pip en métodos __reduce__ eluden la detección de picklescan y logran la ejecución remota de código al invocar pickle.load().
