langchain is vulnerable to Server-Side Request Forgery. This vulnerability exists because it does not properly filter URLs in the __init__ function in recursive_url_loader.py, allowing an attacker to trick a server into sending HTTP requests to any domain by taking advantage of the server’s capacity to crawl from an external server to an internal server.
