Background

loopback-connector-mongodb is a MongoDB connector for LoopBack, a highly-extensible, open-source Node.js framework for building APIs and microservices. It allows developers to connect their LoopBack applications to MongoDB databases, enabling data storage and retrieval. However, versions prior to 3.6.0 of loopback-connector-mongodb are vulnerable to NoSQL injection.

Vulnerability Detail

NoSQL injection is a type of injection attack that targets NoSQL databases, such as MongoDB. In the case of loopback-connector-mongodb, the vulnerability arises from the failure to properly sanitize a filter passed to query the database. This allows the dangerous $where property to be passed to the MongoDB Driver, which can execute JavaScript code on the database. This feature, while intended by MongoDB, can be exploited by malicious actors to perform unauthorized operations or execute arbitrary code on the database. An example of a malicious query is provided in the vulnerability details.

How To Fix

Latest published version: 8.0.3 as of 23 Oct 2026 

npm install loopback-connector-mongodb@8.0.3

Upgrading to it may include breaking changes; the version below is the minimum fixed release for this vulnerability.

If you need the minimum change

3.6.0

This is the first release that contains the fix.

npm install loopback-connector-mongodb@3.6.0
