Description
### Impact 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. ### Patches This problem is fixed starting with version `3.9`. ### Workarounds Only load models from trusted sources and model archives created with Keras. ### References - https://www.cve.org/cverecord?id=CVE-2025-1550 - https://github.com/keras-team/keras/pull/20751
