Keras: HDF5 links can disclose local file contents

A vulnerability in keras-team/keras versions = 3.14.0 allows arbitrary local HDF5 file content disclosure due to improper handling of HDF5 ExternalLinks. The KerasFileEditor and keras.saving.loadweights functions bypass the safegeth5group and safegeth5dataset helpers, which are designed to reject...

PYSEC-2026-2546 Keras has a Local File Disclosure via HDF5 External Storage During Keras Weight Loading

Summary TensorFlow / Keras continues to honor HDF5 “external storage” and ExternalLink features when loading weights. A malicious .weights.h5 or a .keras archive embedding such weights can direct loadweights to read from an arbitrary readable filesystem path. The bytes pulled from that path...

📄 Google Keras 3.13.0 Denial of Service

A denial of service vulnerability exists in the HDF5 weight loading component of Google Keras versions 3.0.0 through 3.13.0 on all platforms. The vulnerability is caused by the absence of any validation or throttling when processing HDF5 dataset shape metadata declared inside a .keras archive...
