CVE-2026-31222

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.

Summary		(es) 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.
