Summary
Workarounds
Only load models from trusted sources and model archives created with Keras.
References
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.
Untrusted input is evaluated as executable code within the application's runtime environment. Typical impact: arbitrary code execution within the application's privilege context.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
This problem is fixed starting with version 3.9.
Frequently Asked Questions
- What is CVE-2025-1550? CVE-2025-1550 is a high-severity code injection vulnerability in keras (pip), affecting versions >= 3.0.0, < 3.9.0. It is fixed in 3.9.0. Untrusted input is evaluated as executable code within the application's runtime environment.
- Which versions of keras are affected by CVE-2025-1550? keras (pip) versions >= 3.0.0, < 3.9.0 is affected.
- Is there a fix for CVE-2025-1550? Yes. CVE-2025-1550 is fixed in 3.9.0. Upgrade to this version or later.
- Is CVE-2025-1550 exploitable, and should I be worried? Whether CVE-2025-1550 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-1550 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
