Abandoned and Unmaintained Packages

Impact: HIGH (No upstream fixes for bugs, CVEs, or runtime upgrades)

A package without a release in 24+ months, with open critical issues, or with the maintainer publicly stepping away is abandonware. The next CVE, the next Node/PHP version, or the next breaking dep change becomes your problem to fix.

How to Detect

Indicators to check on each direct dependency:

• Last release date (npm view <pkg> time.modified, composer info <pkg>)
• Open issues vs closed ratio (high open count, no recent triage)
• Maintainer activity (last commit > 2 years ago)
• Explicit deprecation (npm view <pkg> deprecated)
• Known alternatives community has migrated to

# Node
npm view <pkg> time.modified deprecated
npx npm-check                       # flags deprecated packages
npx snyk test                       # warns on unmaintained packages

# PHP
composer info <pkg>                 # shows abandoned status from packagist
composer audit                      # also reports abandonment

Incorrect

// ❌ Depending on packages flagged as abandoned or deprecated
{
  "dependencies": {
    "request": "^2.88.0",            // deprecated 2020 by maintainer
    "node-uuid": "^1.4.8",           // replaced by `uuid` years ago
    "moment": "^2.29.0",             // maintenance-only since 2020, deprecated by author
    "babel-eslint": "^10.1.0"        // replaced by @babel/eslint-parser
  }
}

Problems:

• request has an open CVE with no upstream fix coming
• moment ships ~290KB of timezone data — date-fns or dayjs do it in 10KB
• Future engineer cannot tell whether these are "trusted core deps" or graveyard residents

Correct

// ✅ Migrated to maintained alternatives
{
  "dependencies": {
    "undici": "^6.0.0",              // replaces `request`
    "uuid": "^9.0.0",                // replaces `node-uuid`
    "date-fns": "^3.0.0",            // replaces `moment`
    "@babel/eslint-parser": "^7.23.0"
  }
}

Benefits:

• CVEs in maintained packages get upstream fixes — you only patch
• Bundle size and runtime characteristics improve
• New engineers don't waste time on packages they "shouldn't have learned"

Remediation Strategy

• Effort: S–M per package (depends on API surface used)
• When to pay down:
  1. Now: any abandoned dep with a known CVE
  2. This quarter: any abandoned dep blocking a runtime upgrade
  3. Opportunistically: the rest, when you're already touching that code path

Tip: When forced to keep an abandoned dep temporarily, lock the version exactly, document why in a comment in the manifest, and create a tracking issue.
