CVE-2026-7584

Full vulnerability record from the local CVENow database.

Description

The LabOne Q serialization framework uses a class-loading mechanism (import_cls) to dynamically import and instantiate Python classes during deserialization. Prior to the fix, this mechanism accepted arbitrary fully-qualified class names from the serialized data without any validation of the target class or restriction on which modules could be imported. 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.

      "value": "El framework de serialización de LabOne Q utiliza un mecanismo de carga de clases (import_cls) para importar e instanciar dinámicamente clases de Python durante la deserialización. Antes de la corrección, este mecanismo aceptaba nombres de clase arbitrarios completamente cualificados de los datos serializados sin ninguna validación de la clase objetivo ni restricción sobre qué módulos podían importarse. Un atacante puede crear un archivo de experimento serializado que hace que el motor de deserialización importe e instancie clases de Python arbitrarias con argumentos de constructor controlados por el atacante, lo que resulta en ejecución de código arbitrario en el contexto del usuario que ejecuta el proceso de Python. La explotación requiere que la víctima cargue un archivo malicioso utilizando las funciones de deserialización de LabOne Q, por ejemplo, un archivo de experimento comprometido compartido con fines de colaboración o soporte."
