How to Fix CVE-2021-29369

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

@rkesters/gnuplot fixed: 0.1.1 
npm install @rkesters/gnuplot@0.1.1
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 @rkesters/gnuplot

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-29369, inspect your project dependencies using npm:

npm ls @rkesters/gnuplot

Analyze the terminal output to locate any version of @rkesters/gnuplot in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.1), your application is affected.

Note: The npm ls @rkesters/gnuplot 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-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In @rkesters/gnuplot, 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

@rkesters/gnuplot is an easy to use node module to draw charts using gnuplot and ps2pdf. The gnuplot package prior to version 0.1.0 for Node.js allows code execution via shell metacharacters in Gnuplot commands.
