How to Fix CVE-2023-34541

To remediate this vulnerability, upgrade all affected Langchain 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 fixed: 0.0.247 
pip install langchain>=0.0.247
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

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-34541, inspect your installed packages using pip:

pip show langchain

Analyze the terminal output to locate any version of Langchain in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.247), your application is affected.

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