Security Update Script

Overview

This directory contains the security-pin-update.js script that helps protect against malicious npm packages identified in GitHub Advisory Database issue #6099.

Affected Packages

The following packages have been identified as containing malware in specific versions:

Package	Malicious Version	Safe Version
debug	4.4.2	4.4.1
color-convert	3.1.1	2.0.1
backslash	0.2.1	0.2.0
error-ex	1.3.3	1.3.2
simple-swizzle	0.2.3	0.2.2
is-arrayish	0.3.3	0.3.2
color-name	2.0.1	1.1.4
color-string	2.1.1	1.9.1

Usage

Running the Security Update

From the project root directory:

node scripts/security-pin-update.js

What the Script Does

1. Checks current versions - Identifies which affected packages are installed
2. Creates backup - Makes a timestamped backup of your package.json
3. Adds pnpm overrides - Pins all affected packages to safe versions
4. Reinstalls dependencies - Forces a clean install with the safe versions
5. Verifies installation - Confirms safe versions are being used

Script Output

The script provides detailed logging:

• ✅ Success indicators for completed actions
• ⚠️ Warnings for existing overrides that will be updated
• ℹ️ Information about current state
• 🔍 Verification of installed versions

How It Works

The script uses pnpm's override feature to force specific versions of packages, even when they're transitive dependencies. This ensures that even if a parent package requires a malicious version, the safe version will be used instead.

Example of what gets added to package.json:

{
  "pnpm": {
    "overrides": {
      "debug": "4.4.1",
      "color-convert": "2.0.1",
      "error-ex": "1.3.2"
    }
  }
}

Recovery

If you need to revert the changes:

1. Restore from backup:

   cp package.json.backup.[timestamp] package.json

2. Remove node_modules and reinstall:

   rm -rf node_modules pnpm-lock.yaml
   pnpm install

Removing Overrides

Once the npm ecosystem has recovered and safe versions are published, you should remove the overrides:

1. Delete the pnpm.overrides section from package.json
2. Run pnpm install to get the latest safe versions

Verification

To verify the script is working:

# Check what versions are actually resolved
pnpm list debug color-convert error-ex simple-swizzle is-arrayish color-name color-string --depth=1

# All should show the safe versions specified in the script

Important Notes

• This is a temporary measure until the npm ecosystem recovers
• Test your application after running the script
• Monitor security advisories for updates
• Remove overrides when no longer needed to get security updates

Support

If you encounter issues:

1. Check the backup files created by the script
2. Ensure pnpm is installed and up to date
3. Run from the project root directory
4. Check file permissions
