How to Fix CVE-2021-4329

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

json-logic-js fixed: 2.0.1 
npm install json-logic-js@2.0.1
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 json-logic-js

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-4329, inspect your project dependencies using npm:

npm ls json-logic-js

Analyze the terminal output to locate any version of Json logic js in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.1), your application is affected.

Note: The npm ls json-logic-js 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-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In Json logic js, 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 vulnerability, which was classified as critical, has been found in json-logic-js 2.0.0. Affected by this issue is some unknown functionality of the file logic.js. The manipulation leads to command injection. Upgrading to version 2.0.1 is able to address this issue. The name of the patch is c1dd82f5b15d8a553bb7a0cfa841ab8a11a9c227. It is recommended to upgrade the affected component. VDB-222266 is the identifier assigned to this vulnerability.
