Summary

In LangChain through 0.0.131, the LLMMathChain chain allows prompt injection attacks that can execute arbitrary code via the Python exec() method.

Impact

What is code injection?

Untrusted input is evaluated as executable code within the application's runtime environment. Typical impact: arbitrary code execution within the application's privilege context.

Severity and exposure

CVE-2023-29374 has a CVSS score of 9.8 (Critical). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.

No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

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 instead of chasing every advisory.

Kodem's Application Detection and Response identifies whether CVE-2023-29374 is reachable in your applications. Explore runtime application protection for your team.

Remediation advice

No fixed version is listed for CVE-2023-29374 yet.

In the interim: Never evaluate untrusted input as code. Use sandboxed evaluation environments if dynamic execution is required.

Frequently asked questions about CVE-2023-29374

What is CVE-2023-29374?

CVE-2023-29374 is a critical-severity code injection vulnerability in langchain (pip), affecting versions <= 0.0.131. No fixed version is listed yet. Untrusted input is evaluated as executable code within the application's runtime environment.

How severe is CVE-2023-29374?

CVE-2023-29374 has a CVSS score of 9.8 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which versions of langchain are affected by CVE-2023-29374?

langchain (pip) versions <= 0.0.131 is affected.

Is there a fix for CVE-2023-29374?

No fixed version is listed for CVE-2023-29374 yet. Monitor the advisory for updates and apply mitigations in the interim.

Is CVE-2023-29374 exploitable, and should I be worried?

Whether CVE-2023-29374 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-2023-29374 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.

How do I fix CVE-2023-29374?

No fixed version is listed yet. In the interim: Never evaluate untrusted input as code. Use sandboxed evaluation environments if dynamic execution is required.
