CVE

DEBIAN-CVE-2025-9905

The Keras Model.load_model method can be exploited to achieve arbitrary code execution, even with safe_mode=True.

The Keras Model.loadmodel method can be exploited to achieve arbitrary code execution, even with safemode=True.  One can create a specially crafted .h5/.hdf5 model archive that, when loaded via Model.loadmodel, will trigger arbitrary code to be executed.  This is achieved by crafting a special .h5 archive file that uses the Lambda layer feature of keras which allows arbitrary Python code in the form of pickled code. The vulnerability comes from the fact that the safemode=True option is not honored when reading .h5 archives.  Note that the .h5/.hdf5 format is a legacy format supported by Keras 3 for backwards compatibility.
