Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The module npm-script-demo opened a connection to a command and control server. It has been removed from the npm registry.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The npm-script-demo package was a malicious module that established outbound connections to a threat actor's command and control server, effectively functioning as a backdoor or remote access mechanism. This represents a supply chain compromise where a malicious package was published to the public npm registry.

MitigationAudit all project dependencies and npm install logs to identify if npm-script-demo was ever installed, remove the package from any systems where found, and conduct forensic review of affected systems for indicators of compromise or unauthorized access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check package.json for the malicious package
    Search for 'npm-script-demo' in your project's package.json file, specifically in the dependencies or devDependencies sections
    Affected if The package name npm-script-demo appears in dependencies with version 0.0.1
  2. Verify package installation in node_modules
    Run 'ls node_modules | grep npm-script-demo' or check if the directory node_modules/npm-script-demo exists
    Affected if The npm-script-demo directory exists in node_modules
  3. Query npm for installed package
    Run 'npm list npm-script-demo' or 'npm list --depth=0' to see installed packages
    Affected if npm-script-demo appears in the npm list output
  4. Check for the specific malicious version
    Run 'npm list npm-script-demo --depth=0' and verify if version 0.0.1 is installed
    Affected if Version 0.0.1 of npm-script-demo is shown as installed
  5. Review npm installation logs
    Check your npm install logs, build logs, or CI/CD logs for any past installations of npm-script-demo
    Affected if The package was ever installed in the project history

If npm-script-demo version 0.0.1 is found in package.json, node_modules, or installation history, the environment is affected by this supply chain compromise.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Audit all project dependencies and npm install logs to identify if npm-script-demo was ever installed, remove the package from any systems where found, and conduct forensic review of affected systems for indicators of compromise or unauthorized access.

Recommended fix High confidence
  1. Remove the npm-script-demo package from your project dependencies immediately
  2. Run 'npm uninstall npm-script-demo' to remove the package
  3. Check your package-lock.json and yarn.lock to ensure the malicious package is not present
  4. Search your codebase for any references to this package and remove them
  5. Audit your project for any other unknown or suspicious dependencies
  6. Consider rotating any credentials or secrets that may have been exposed if the package was installed
Caveat N/A - the package is malicious and should not be used; find an alternative legitimate solution for whatever functionality was needed
