GHSA-H59X-P739-982C

Vulnerability from github – Published: 2024-03-04 00:30 – Updated: 2024-03-14 23:14

Summary

LangChain directory traversal vulnerability

Details

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.
