CVE-2024-28088: Langchain

High severity, CVSS 8.1. EPSS: 1.7% chance of exploitation in the next 30 days.

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 Langchain: before 0.1.12 (fixed in 0.1.12)
