Specifically, the `_raise_for_lambda_deserialization()` function fails to enforce the safe-mode guard when `safe_mode` is set to `None`, which is the default value when `from_config()` is called outside of a `SafeModeScope` context. This logic error conflates `None` (unset/default-deny) with `False` (explicitly disabled), bypassing the guard and allowing attacker-controlled `marshal` bytecode to be deserialized. Affected call sites include `keras.layers.deserialize(config)`, `keras.models.clone_model(model)`, and any direct invocation of `Lambda.from_config(config)` without an enclosing `SafeModeScope(True)`. This vulnerability can be exploited to achieve arbitrary OS-level code execution in the context of the server or user process."}, {"lang": "es", "value": "Una vulnerabilidad en keras-team/keras versi\u00f3n 3.14.0 permite la ejecuci\u00f3n de c\u00f3digo arbitrario debido a un manejo inadecuado de la deserializaci\u00f3n en la capa \u2019Lambda\u2019.
