SCA: security update for langchain-core (GHSA-qh6h-p6c9-ff54)

high Tenable Self-Hosted Container Security Plugin ID 439582

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 version 1.2.22,
 multiple functions in langchain_core.prompts.loading read files from paths embedded in deserialized config
 dicts without validating against directory traversal or absolute path injection. When an application
 passes user-influenced prompt configurations to load_prompt() or load_prompt_from_config(), an attacker
 can read arbitrary files on the host filesystem, constrained only by file-extension checks (.txt for
 templates, .json/.yaml for examples). This issue has been patched in version 1.2.22. (CVE-2026-34070)

Solution

Update the langchain-core library and its related packages to version 1.2.22 or later.
