TL;DR

Affected versions of this package allow loading of malicious .keras files containing crafted HDF5 metadata with extreme or overflowing tensor shapes, leading to unbounded memory allocation and potential remote denial of service. An attacker could exploit this by supplying a shape bomb that triggers recursive path handling issues or forces NumPy to allocate multi-gigabyte tensors during model loading, exhausting memory or crashing the process before validation occurs.
