SCA: security update for langchain-openai (GHSA-r7w7-9xr2-qq2r)

low Tenable Cloud Security Plugin ID 440915

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 1.1.14, langchain-
 openai's _url_to_size() helper (used by get_num_tokens_from_messages for image token counting) validated
 URLs for SSRF protection and then fetched them in a separate network operation with independent DNS
 resolution. This left a TOCTOU / DNS rebinding window: an attacker-controlled hostname could resolve to a
 public IP during validation and then to a private/localhost IP during the actual fetch. (CVE-2026-41488)

Solution

Update the langchain-openai library and its related packages to version 1.1.14 or later.
