How to Fix CVE-2024-28088

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: 0.0.339 
pip install langchain>=0.0.339
langchain-core fixed: 0.1.30 
pip install langchain-core>=0.1.30
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-2024-28088, 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 0.0.339), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Langchain, 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 through 0.1.10 allows ../ directory traversal by an actor who is able to control the final part of the path parameter in a load_chain call. This bypasses the intended behavior of loading configurations only from the hwchase17/langchain-hub GitHub repository. The outcome can be disclosure of an API key for a large language model online service, or remote code execution.
