Doc Text:
A flaw was found in the `keras` package. This vulnerability allows an attacker to execute unauthorized code on a victim's system. It occurs when a victim loads a specially crafted `.keras` model, even if the `safe_mode` security feature is active. The issue arises because the `keras` package can unconditionally load external TensorFlow SavedModels without sufficient validation, thereby bypassing the intended security protections and leading to arbitrary code execution.

Description OSIDB Bzimport 2026-04-13 15:02:36 UTC 
A vulnerability in the `TFSMLayer` class of the `keras` package, version 3.13.0, allows attacker-controlled TensorFlow SavedModels to be loaded during deserialization of `.keras` models, even when `safe_mode=True`. This bypasses the security guarantees of `safe_mode` and enables arbitrary attacker-controlled code execution during model inference under the victim's privileges. The issue arises due to the unconditional loading of external SavedModels, serialization of attacker-controlled file paths, and the lack of validation in the `from_config()` method.
