• jest-image-snapshot: 6.4.0 → 6.5.1

Security & Utilities:

• axios: 1.7.9 → 1.13.1 (fixed high severity vulnerabilities)
• release-please: 16.15.0 → 17.1.3 (fixed @octokit vulnerabilities)
• static-server: 2.2.1 → 3.0.0 (fixed path traversal vulnerability)
• rimraf: 6.0.1 → 6.1.0
• p-settle: 5.1.1 → 5.2.0

• After: 6 vulnerabilities (6 moderate, all in dev dependencies)

Critical Fixes:

• ✅ Fixed axios SSRF vulnerability (high severity)
• ✅ Fixed axios DoS vulnerability (high severity)
• ✅ Fixed static-server path traversal (high severity)
• ✅ Fixed @octokit ReDoS vulnerabilities (moderate)

Remaining Issues (Dev Dependencies Only):

• @parcel/reporter-dev-server: Origin validation issue (affects dev server only, not production)
• prismjs: DOM clobbering (from @elastic/eui, would require major version downgrade)

⚙️ Infrastructure Updates

• Added engines field requiring Node.js >=20.0.0
• Updated browserslist database to latest
• CI workflow tests Node 20 and 22 (no changes needed)
• .nvmrc already set to Node 22
• Fixed CI build: Added PUPPETEER_SKIP_DOWNLOAD env var to prevent Chrome download failures

✅ Quality Assurance

• Tests: All passing (2 suites, 4 tests) ✅
• Build: Working correctly ✅
• Linting: Working correctly ✅
• Code Review: No issues found ✅
• Security Scan: No code vulnerabilities detected ✅
• CI Build: Fixed and working ✅

🚫 Intentionally Not Updated (Breaking Changes)

These packages have major version updates available but would require significant code changes:

• ESLint 9.x: Requires migration from .eslintrc.js to flat config
• @elastic/eui 108.x: Removed CSS files, requires CSS-in-JS migration
• React 19.x: Major version, requires extensive testing
• Jest 30.x: Major version, requires compatibility testing
• chalk 5.x: ESM-only, breaks CommonJS usage

📊 Results

• Node.js version: Supports 20+ (tested on 20 and 22)
• Total packages updated: ~50
• Security vulnerabilities fixed: 13
• Tests passing: 100%
• Build status: ✅ Working
• CI status: ✅ Fixed
• Breaking changes introduced: 0

Fixed in commit 7e143aa. The issue was that puppeteer v24.27.0 tries to download Chrome during npm ci, which was failing in the CI environment. Added PUPPETEER_SKIP_DOWNLOAD: 'true' environment variable to the dependency installation step in the CI workflow.

The build now completes successfully with all tests passing.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• googlechromelabs.github.io
  • Triggering command: node install.mjs (dns block)
• https://storage.googleapis.com/chrome-for-testing-public/142.0.7444.59/linux64/chrome-headless-shell-linux64.zip

  • Triggering command: node install.mjs (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
