LangChain is a framework for developing applications powered by large language models. LangChain before 0.0.317 allows SSRF via document_loaders/recursive_url_loader.py because crawling can proceed from an external server to an internal server.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
