CVE-2025-8747Public exploitNetwork attack vector

Code execution via approved-module function deserialization

Published Aug 11, 2025 · Updated Feb 26, 2026

Unsafe deserialization in Google Keras 3.0.0 through 3.10.0 allows attackers to execute code when a user loads a crafted .keras archive. Keras safe_mode permits a Lambda layer to invoke built-in functions from approved modules; crafted get_file arguments download files to attacker-chosen paths. Loading an untrusted model is required, and arbitrary file overwrite enables code execution when a sensitive executable or configuration file is replaced.
