CVE-2026-8597

Missing integrity verification in the Triton inference handler in Amazon SageMaker Python SDK v2 before v2.257.2 and v3 before v3.8.0 might allow a remote authenticated actor to achieve code execution in inference containers via replacement of model artifacts in S3 with a specially crafted pickle payload that is deserialized without verification. This issue requires a remote authenticated actor with S3 write access to the model artifact path. To remediate this issue, we recommend upgrading to Amazon SageMaker Python SDK v2.257.2 or v3.8.0 and rebuild any Triton models previously created with ModelBuilder using the updated SDK.

Summary		(es) Falta de verificación de integridad en el gestor de inferencia de Triton en el SDK de Python de Amazon SageMaker v2 anterior a la v2.257.2 y v3 anterior a la v3.8.0 podría permitir a un actor remoto autenticado lograr la ejecución de código en contenedores de inferencia mediante el reemplazo de artefactos del modelo en S3 con una carga útil pickle especialmente diseñada que se deserializa sin verificación. Este problema requiere un actor remoto autenticado con acceso de escritura a S3 a la ruta del artefacto del modelo. Para remediar este problema, recomendamos actualizar al SDK de Python de Amazon SageMaker v2.257.2 o v3.8.0 y reconstruir cualquier modelo de Triton creado previamente con ModelBuilder usando el SDK actualizado.
