SCA: security update for langchain-core (GHSA-pjwx-r37v-7724)

high Tenable Cloud Security Plugin ID 441570

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 0.3.85 and 1.3.3,
 LangChain contains older runtime code paths that deserialize run inputs, run outputs, or other
 application-controlled payloads using overly broad object allowlists. These paths may call load() with
 allowed_objects="all". This does not enable arbitrary Python object deserialization, but it does allow any
 trusted LangChain-serializable object to be revived, which is broader than these runtime paths require. As
 a result, attacker-supplied LangChain serialized constructor dictionaries may cause trusted runtime paths
 to instantiate classes with untrusted constructor arguments. This vulnerability is fixed in 0.3.85 and
 1.3.3. (CVE-2026-44843)

Solution

Update the langchain-core library and its related packages to version 0.3.85 or later.
