      "value": "Keras versions up to and including 3.13.2 are vulnerable to an arbitrary HDF5 file read due to an incomplete fix for CVE-2026-1669. The vulnerability resides in the `H5IOStore._verify_dataset()` and `file_editor.py` methods, which fail to check the `dataset.is_virtual` property of HDF5 datasets. This allows an attacker to craft a malicious `.keras` model archive or `.h5` weights file containing a Virtual Dataset (VDS) that references external HDF5 files on the victim's filesystem. When the victim loads the model using `keras.models.load_model()` or `keras.saving.load_model()`, the external file is transparently read, leading to potential information disclosure. Fixed in versions 3.12.2 and 3.14.1."

      "value": "Las versiones de Keras hasta la 3.13.2 inclusive son vulnerables a una lectura arbitraria de archivos HDF5 debido a una corrección incompleta para CVE-2026-1669. La vulnerabilidad reside en los métodos “H5IOStore._verify_dataset()” y “file_editor.py”, que no verifican la propiedad “dataset.is_virtual” de los conjuntos de datos HDF5. Esto permite a un atacante crear un archivo de modelo .keras malicioso o un archivo de pesos .h5 que contiene un Conjunto de Datos Virtual (VDS) que hace referencia a archivos HDF5 externos en el sistema de archivos de la víctima. Cuando la víctima carga el modelo usando “keras.models.load_model()” o “keras.saving.load_model()”, el archivo externo se lee de forma transparente, lo que lleva a una potencial revelación de información. Corregido en las versiones 3.12.2 y 3.14.1."
