PyPI: langchain
CVE-2024-28088
Safety vulnerability ID: SFTY-20240304-63735
Safety legacy ID: pyup.io-66051
Affected versions of the LangChain package are vulnerable to Path Traversal due to improper sanitization of the path parameter in the `load_chain` call. The `load_chain` function allows user input to manipulate the final part of the path, enabling traversal outside the intended directory scope. An attacker can exploit this by crafting a path that accesses sensitive files, potentially leading to Information Disclosure of API keys or even Remote Code Execution if malicious scripts are executed.
