• EPSS: 1.7% probability of exploitation in the next 30 days

Description

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. (A patch is available as of release 0.1.29 of langchain-core.)

Affected products

• langchain-ai/langchain: before 0.1.12 — fixed in 0.1.12

How to fix

Upgrade to a fixed version: langchain-ai/langchain 0.1.12. Check the vendor advisory for mitigations.
