How to Fix CVE-2024-38459

To remediate this vulnerability, upgrade all affected Langchain experimental dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

langchain-experimental fixed: 0.0.61 
pip install langchain-experimental>=0.0.61
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show langchain-experimental

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-38459, inspect your installed packages using pip:

pip show langchain-experimental

Analyze the terminal output to locate any version of Langchain experimental in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.61), your application is affected.

Note: The pip show langchain-experimental command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-276: Incorrect Default Permissions, where during installation, installed file permissions are set to allow anyone to modify those files. In Langchain experimental, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

langchain_experimental (aka LangChain Experimental) before 0.0.61 for LangChain provides Python REPL access without an opt-in step. NOTE; this issue exists because of an incomplete fix for CVE-2024-27444.
