| 标题 | langchain-ai langchain 0.1.9 Remote Code Execution (RCE) |
|---|
| 描述 | A command execution vulnerability exists in the `langchain` project version `0.1.9`.
The code in line `106` of the `libs/community/langchain_community/retrievers/tfidf.py` file in this project have a function named `load_local`. There are two unsecured functions `joblib.load` and `pickle.load` in this function, and By constructing the malicious file, I generated the `tfidf_vectorizer.jobli`b and `tfidf_vectorizer.pkl` files in the PoC.pkl directory. They both contain strings that can be executed remotely by command., which, by not using a more secure way of loading and checking external files, resulted in being able to trigger a command execution that triggers an RCE via the commands contained in the malicious files. |
