CVE-2026-26019 (opens in a new tab)How to fix?
Upgrade @langchain/community to version 1.1.14 or higher.
Overview
@langchain/community is a Third-party integrations for LangChain.js
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the RecursiveUrlLoader class. An attacker can access internal or sensitive resources by influencing crawled page content to include links that bypass origin and IP address validation, causing the process to fetch attacker-controlled or internal URLs.
Note: This is only exploitable if the process runs in an environment with access to internal networks or cloud metadata services.
Workaround
This vulnerability can be mitigated by avoiding the use of RecursiveUrlLoader on untrusted or user-influenced content, or by running the crawler in a network environment without access to cloud metadata or internal services.
