CVE-2025-71364

picklescan before 0.0.30 fails to detect the asyncio.unix_events._UnixSubprocessTransport._start function in pickle reduce methods, allowing remote code execution. Attackers can craft malicious pickle files embedding this built-in function that evade detection but execute arbitrary commands when loaded.

Summary		(es) picklescan anterior a la versión 0.0.30 no detecta la función asyncio.unix_events._UnixSubprocessTransport._start en los métodos 'reduce' de pickle, lo que permite la ejecución remota de código. Los atacantes pueden crear archivos pickle maliciosos que incrustan esta función incorporada, los cuales evaden la detección pero ejecutan comandos arbitrarios al cargarse.
