SCA: security update for @langchain/mongodb (GHSA-m6rx-h84q-8r95)

medium Tenable Cloud Security Plugin ID 473852

Description

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

 - LangChain is a framework for building LLM-powered applications. Prior to 1.3.1, MongoDBChatMessageHistory
 does not enforce the documented string type for an untrusted structured session identifier at runtime,
 allowing the identifier to be interpreted as a MongoDB query condition rather than as a literal value when
 multiple users' histories are stored in a shared MongoDB collection. An attacker able to invoke chat-
 history operations can read, modify, or delete another user's stored conversation. Applications using
 authenticated, server-controlled string identifiers are not affected. This issue is fixed in version
 1.3.1. (CVE-2026-106119)

Solution

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