Echo: langchain-openai: security update to 1.1.14

low Tenable Self-Hosted Container Security Plugin ID 457407

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.
