LangChain directory traversal vulnerability
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| PyPI | langchain | < 0.0.339 | 0.0.339 |
| PyPI | langchain-core | < 0.1.30 | 0.1.30 |
Details
As written in the advisory (Markdown source, shown as plain text).
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.
