CVE-2026-1462Public exploitNetwork attack vector

Code execution via unchecked TFSMLayer deserialization

Published Apr 13, 2026 · Updated Apr 13, 2026

Untrusted deserialization in Keras before 3.13.2 allows remote attackers to execute code by supplying a crafted .keras model. TFSMLayer.from_config accepts the serialized filepath and instantiates a layer that loads executable graph code from the external SavedModel without honoring safe mode. Execution requires a recipient to load the crafted model and occurs during inference with the privileges of the loading process.
