SCA: security update for langchain-text-splitters (GHSA-fv5p-p927-qmxr)

medium Tenable Self-Hosted Container Security Plugin ID 440917

Description

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

 - LangChain is a framework for building agents and LLM-powered applications. Prior to langchain-text-
 splitters 1.1.2, HTMLHeaderTextSplitter.split_text_from_url() validated the initial URL using
 validate_safe_url() but then performed the fetch with requests.get() with redirects enabled (the default).
 Because redirect targets were not revalidated, a URL pointing to an attacker-controlled server could
 redirect to internal, localhost, or cloud metadata endpoints, bypassing SSRF protections. The response
 body is parsed and returned as Document objects to the calling application code. Whether this constitutes
 a data exfiltration path depends on the application: if it exposes Document contents (or derivatives) back
 to the requester who supplied the URL, sensitive data from internal endpoints could be leaked.
 Applications that store or process Documents internally without returning raw content to the requester are
 not directly exposed to data exfiltration through this issue. This vulnerability is fixed in 1.1.2.
 (CVE-2026-41481)

Solution

Update the langchain-text-splitters library and its related packages to version 1.1.2 or later.
