An attacker can craft a serialized experiment file that causes the deserialization engine to import and instantiate arbitrary Python classes with attacker-controlled constructor arguments, resulting in arbitrary code execution in the context of the user running the Python process. Exploitation requires the victim to load a malicious file using LabOne Q's deserialization functions, for example a compromised experiment file shared for collaboration or support purposes."}, {"lang": "es", "value": "El framework de serializaci\u00f3n de LabOne Q utiliza un mecanismo de carga de clases (import_cls) para importar e instanciar din\u00e1micamente clases de Python durante la deserializaci\u00f3n.
