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...
