📄 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...

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...
