The Keras `Model.load_model` method **silently** ignores `safe_mode=True` and allows arbitrary code execution when a `.h5`/`.hdf5` file is loaded.

Note: This report has already been discussed with the Google OSS VRP team, who recommended that I reach out directly to the Keras team. I’ve chosen to do so privately rather than opening a public issue, due to the potential security implications. I also attempted to use the email address listed i...

GHSA-36FQ-JGMW-4R9C Keras is vulnerable to Deserialization of Untrusted Data

Arbitrary Code Execution in Keras Keras versions prior to 3.11.0 allow for arbitrary code execution when loading a crafted .keras model archive, even when safemode=True. The issue arises because the archive’s config.json is parsed before layer deserialization. This can invoke...
