How to Fix CVE-2024-36574

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

@allanlancioni/flatten-json fixed: Latest secure release 
npm install @allanlancioni/flatten-json@Latest secure release
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 @allanlancioni/flatten-json

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-36574, inspect your project dependencies using npm:

npm ls @allanlancioni/flatten-json

Analyze the terminal output to locate any version of @allanlancioni/flatten json in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The npm ls @allanlancioni/flatten-json 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-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), where the product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype. In @allanlancioni/flatten json, 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

A Prototype Pollution issue in flatten-json 1.0.1 allows an attacker to execute arbitrary code via module.exports.unflattenJSON (flatten-json/index.js:42)
