CVE-2025-1550Public exploit

Code execution via unrestricted deserialization imports

Published Mar 11, 2025 · Updated Jul 24, 2025

Code injection in Google Keras 3.0.0 through 3.7.0 allows attackers to execute Python code when a crafted .keras model is loaded. The _retrieve_class_or_fn helper imports any module named by config.json and returns its named function, while functional model reconstruction invokes that function with attacker-controlled inbound-node arguments. Loading an untrusted model is required; execution occurs during parsing with the Keras process permissions even when safe_mode is enabled.
