CVE-2023-46229Public exploitNetwork attack vector

Internal resource access via recursive URL crawling

Published Oct 19, 2023 · Updated Sep 12, 2024

SSRF in LangChain before 0.0.317 allows remote attackers to access internal services through RecursiveUrlLoader crawling. RecursiveUrlLoader follows child links supplied by an external page and issues server-side GET requests without reliably excluding internal destinations. Exploitation requires an application to crawl attacker-influenced content and exposes resources reachable from the application's network context.
