langchain is vulnerable to Server-Side Request Forgery. The vulnerability is due to improper validation of URLs, allowing the inclusion of external links even when prevent_outside is set to True, by not adequately comparing the domain of the base URL with the domain of the links being processed. This flaw potentially leads to Server-Side Request Forgery.
