SCA: security update for @langchain/langgraph-checkpoint-mongodb (GHSA-98xf-r82g-9mhx)

medium Tenable Cloud Security Plugin ID 443124

Description

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

 - @langchain/langgraph-checkpoint-mongodb provides a LangGraph.js CheckpointSaver implementation that uses
 MongoDB for storage. Versions 1.3.0 and below are vulnerable to NoSQL injection: checkpoint identifiers
 (thread_id, checkpoint_ns, checkpoint_id) from config.configurable are passed into MongoDB find() queries
 in MongoDBSaver.getTuple() without type enforcement. If an attacker supplies an object payload (such as
 MongoDB operators $gt or $ne) instead of a string, it can be interpreted as a query operator, bypassing
 thread scoping and leaking checkpoints, including pending writes, across tenants. Applications are at risk
 if they forward untrusted input into config.configurable without coercing it to strings or validating it
 against a schema, particularly in multi-tenant or user-isolated setups. Apps that only use server-issued,
 string-typed identifiers with schema validation rejecting non-string fields are not affected. This issue
 has been fixed in version 1.3.1. (CVE-2026-48121)

Solution

Update the @langchain/langgraph-checkpoint-mongodb library and its related packages to version 1.3.1 or later.
