Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Keras versions below 3.12.3, and from 3.13.0 up to but not including 3.15.0, are vulnerable. An attacker who supplies a malicious .h5, .weights.h5, or .keras file containing HDF5 external links can cause Keras to read data from other HDF5 files on the victim's local filesystem, disclosing sensitive contents. Upgrade to Keras 3.12.3 or 3.15.0. The source gives no workaround.
