How to Fix GHSA-m734-r4g6-34f9

To remediate this vulnerability, upgrade all affected Loopback connector mongodb dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

loopback-connector-mongodb fixed: 3.6.0 
npm install loopback-connector-mongodb@3.6.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls loopback-connector-mongodb

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-m734-r4g6-34f9, inspect your project dependencies using npm:

npm ls loopback-connector-mongodb

Analyze the terminal output to locate any version of Loopback connector mongodb in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.6.0), your application is affected.

Note: The npm ls loopback-connector-mongodb command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Loopback connector mongodb, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Versions of `loopback-connector-mongodb` before 3.6.0 are vulnerable to NoSQL injection. MongoDB Connector for LoopBack fails to properly sanitize a filter passed to query the database by allowing the dangerous `$where` property to be passed to the MongoDB Driver. The Driver allows the special `$where` property in a filter to execute JavaScript (client can pass in a malicious script) on the database Driver. This is an [intended feature of MongoDB](https://docs.mongodb.com/manual/core/server-side-javascript/) unless disabled ([instructions here](https://docs.mongodb.com/manual/core/server-side-javascript/#disable-server-side-js)). A proof of concept malicious query: ``` GET /POST filter={"where": {"$where": "function(){sleep(5000); return this.title.contains('Hello');}"}} ``` The above makes the database sleep for 5 seconds and then returns all “Posts” with the title containing the word `Hello`. ## Recommendation Update to version 3.6.0 or later.
