Echo: @langchain/community: security update to 1.1.14

medium Tenable Self-Hosted Container Security Plugin ID 464716

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - LangChain is a framework for building LLM-powered applications. Prior to 1.1.14, the RecursiveUrlLoader
 class in @langchain/community is a web crawler that recursively follows links from a starting URL. Its
 preventOutside option (enabled by default) is intended to restrict crawling to the same site as the base
 URL. The implementation used String.startsWith() to compare URLs, which does not perform semantic URL
 validation. An attacker who controls content on a crawled page could include links to domains that share a
 string prefix with the target, causing the crawler to follow links to attacker-controlled or internal
 infrastructure. Additionally, the crawler performed no validation against private or reserved IP
 addresses. A crawled page could include links targeting cloud metadata services, localhost, or RFC 1918
 addresses, and the crawler would fetch them without restriction. This vulnerability is fixed in 1.1.14.
 (CVE-2026-26019)

Solution

Update the @langchain/community library and its related packages to version 1.1.14 or later.
