DescriptionCVE.org

The Keras Model.load_model function permits arbitrary code execution, even with safe_mode=True, through a manually constructed, malicious .keras archive. By altering the config.json file within the archive, an attacker can specify arbitrary Python modules and functions, along with their arguments, to be loaded and executed during model loading.

AnalysisAI

Keras Model.load_model can execute arbitrary code even with safe_mode=True by manipulating the config.json inside a .keras archive. An attacker can specify arbitrary Python modules and functions to be loaded during model deserialization. PoC available, patch available.

Technical ContextAI

The .keras archive format includes a config.json that specifies which Python classes to instantiate. While safe_mode=True restricts certain operations, the validation is insufficient (CWE-94) – an attacker can reference arbitrary Python modules and functions with controlled arguments in the config.

Affected ProductsAI

Keras (versions before the fix)

RemediationAI

Update Keras to the latest patched version. Never load models from untrusted sources, even with safe_mode=True. Validate model provenance before loading.
