      "value": "The snorkel library thru v0.10.0 contains an insecure deserialization vulnerability (CWE-502) in the Trainer.load() method of the Trainer class. The method loads model checkpoint files using torch.load() without enabling the security-restrictive weights_only=True parameter. This default behavior allows the deserialization of arbitrary Python objects via the Pickle module. A remote attacker can exploit this by providing a maliciously crafted model file, leading to arbitrary code execution on the victim's system when the file is loaded via the vulnerable method."

      "value": "La biblioteca snorkel hasta la v0.10.0 contiene una vulnerabilidad de deserialización insegura (CWE-502) en el método Trainer.load() de la clase Trainer. El método carga archivos de punto de control del modelo usando torch.load() sin habilitar el parámetro restrictivo de seguridad weights_only=True. Este comportamiento predeterminado permite la deserialización de objetos Python arbitrarios a través del módulo Pickle. Un atacante remoto puede explotar esto al proporcionar un archivo de modelo creado maliciosamente, lo que lleva a la ejecución de código arbitrario en el sistema de la víctima cuando el archivo es cargado a través del método vulnerable."
