CVE-2024-28088: LangChain directory traversal in load_chain path parameter

Summary

CVE-2024-28088 affects LangChain through 0.1.10. An actor who can control the final part of the path parameter in a load_chain call can use ../ directory traversal to bypass the intended restriction on loading configurations only from the hwchase17/langchain-hub GitHub repository. The source says the outcome can be disclosure of an API key for a large language model online service, or remote code execution.
