GitHub Vulnerability Alerts

CVE-2025-1550

Impact

The Keras Model.load_model function permits arbitrary code execution, even with safe_mode=True, through a manually constructed, malicious .keras archive. By altering the config.json file within the archive, an attacker can specify arbitrary Python modules and functions, along with their arguments, to be loaded and executed during model loading.

Patches

This problem is fixed starting with version 3.9.

Workarounds

Only load models from trusted sources and model archives created with Keras.

New: OpenVINO backend

OpenVINO is now available as an infererence-only Keras backend. You can start using it by setting the backend field to "openvino" in your keras.json config file.

OpenVINO is a deep learning inference-only framework tailored for CPU (x86, ARM), certain GPUs (OpenCL capable, integrated and discrete) and certain AI accelerators (Intel NPU).

Because OpenVINO does not support gradients, you cannot use it for training (e.g. model.fit()) -- only inference. You can train your models with the JAX/TensorFlow/PyTorch backends, and when trained, reload them with the OpenVINO backend for inference on a target device supported by OpenVINO.

New: ONNX model export

You can now export your Keras models to the ONNX format from the JAX, TensorFlow, and PyTorch backends.

Just pass format="onnx" in your model.export() call:

##### Export the model as a ONNX artifact
model.export("path/to/location", format="onnx")

##### Load the artifact in a different process/environment
ort_session = onnxruntime.InferenceSession("path/to/location")

##### Run inference
ort_inputs = {
    k.name: v for k, v in zip(ort_session.get_inputs(), input_data)
}
predictions = ort_session.run(None, ort_inputs)
New: Scikit-Learn API compatibility interface

It's now possible to easily integrate Keras models into Sciki-Learn pipelines! The following wrapper classes are available:

  • keras.wrappers.SKLearnClassifier: implements the sklearn Classifier API

  • keras.wrappers.SKLearnTransformer: implements the sklearn Transformer API

API changes

  • Add flash_attention argument to keras.ops.dot_product_attention and to keras.layers.MultiHeadAttention.
  • Add keras.layers.STFTSpectrogram layer (to extract STFT spectrograms from inputs as a preprocessing step) as well as its initializer keras.initializers.STFTInitializer.
  • Add celu, glu, log_sigmoid, hard_tanh, hard_shrink, squareplus activations.
  • Add keras.losses.Circle loss.
  • Add image visualization utilities keras.visualization.draw_bounding_boxes, keras.visualization.draw_segmentation_masks, keras.visualization.plot_image_gallery, keras.visualization.plot_segmentation_mask_gallery.
  • Add double_checkpoint argument to BackupAndRestore to save a fallback checkpoint in case the first checkpoint gets corrupted.
  • Add bounding box preprocessing support to image augmentation layers CenterCrop, RandomFlip, RandomZoom, RandomTranslation, RandomCrop.
  • Add keras.ops.exp2, keras.ops.inner operations.

Performance improvements

  • JAX backend: add native Flash Attention support for GPU (via cuDNN) and TPU (via a Pallas kernel). Flash Attention is now used automatically when the hardware supports it.
  • PyTorch backend: add native Flash Attention support for GPU (via cuDNN). It is currently opt-in.
  • TensorFlow backend: enable more kernel fusion via bias_add.
  • PyTorch backend: add support for Intel XPU devices.

Highlights
  • New file editor utility: keras.saving.KerasFileEditor. Use it to inspect, diff, modify and resave Keras weights files. See basic workflow here.
  • New keras.utils.Config class for managing experiment config parameters.
BREAKING changes
  • When using keras.utils.get_file, with extract=True or untar=True, the return value will be the path of the extracted directory, rather than the path of the archive.
Other changes and additions
  • Logging is now asynchronous in fit(), evaluate(), predict(). This enables 100% compact stacking of train_step calls on accelerators (e.g. when running small models on TPU).
    • If you are using custom callbacks that rely on on_batch_end, this will disable async logging. You can force it back by adding self.async_safe = True to your callbacks. Note that the TensorBoard callback isn't considered async safe by default. Default callbacks like the progress bar are async safe.
  • Added keras.saving.KerasFileEditor utility to inspect, diff, modify and resave Keras weights file.
  • Added keras.utils.Config class. It behaves like a dictionary, with a few nice features:
    • All entries are accessible and settable as attributes, in addition to dict-style (e.g. config.foo = 2 or config["foo"] are both valid)
    • You can easily serialize it to JSON via config.to_json().
    • You can easily freeze it, preventing future changes, via config.freeze().
  • Added bitwise numpy ops:
    • bitwise_and
    • bitwise_invert
    • bitwise_left_shift
    • bitwise_not
    • bitwise_or
    • bitwise_right_shift
    • bitwise_xor
  • Added math op keras.ops.logdet.
  • Added numpy op keras.ops.trunc.
  • Added keras.ops.dot_product_attention.
  • Added keras.ops.histogram.
  • Allow infinite PyDataset instances to use multithreading.
  • Added argument verbose in keras.saving.ExportArchive.write_out() method for exporting TF SavedModel.
  • Added epsilon argument in keras.ops.normalize.
  • Added Model.get_state_tree() method for retrieving a nested dict mapping variable paths to variable values (either as numpy arrays or backend tensors (default)). This is useful for rolling out custom JAX training loops.
  • Added image augmentation/preprocessing layers keras.layers.AutoContrast, keras.layers.Solarization.
  • Added keras.layers.Pipeline class, to apply a sequence of layers to an input. This class is useful to build a preprocessing pipeline. Compared to a Sequential model, Pipeline features a few important differences:
    • It's not a Model, just a plain layer.
    • When the layers in the pipeline are compatible with tf.data, the pipeline will also remain tf.data compatible, independently of the backend you use.
