GHSA-74M6-M3XX-3VMJ Keras model loading is vulnerable to denial of service through HDF5 shape bombs

A vulnerability in keras-team/keras versions 3.15.0 allows for a denial of service DoS attack when loading malicious .keras model files via the keras.models.loadmodel function. The H5IOStore.getitem method in keras/src/saving/savinglib.py does not validate the shape or size of datasets, leading t...

📄 Keras 3.13.0 Malicious ML Model Server HDF5 Shape Bomb

This script is a Flask-based web server that distributes .keras machine learning model files, but it is designed in a malicious way for security research/testing scenarios. The main idea is a denial of service via memory exhaustion, where generated Keras models contain artificially declared...

📄 Keras 3.13.0 HDF5 Shape Bomb Denial of Service

This script is a security research tool demonstrating a denial of service vulnerability in Keras model loading through malicious HDF5 shape bombs. It generates .keras model archives containing artificially declared extremely large tensor shapes designed to force excessive memory allocation during...
