  2. Update loader-utils to 2.0.3 - Critical severity (CVSS 9.8) prototype pollution (Alert Bump loader-utils from 2.0.2 to 2.0.4Β #9)
  3. Update webpack-dev-middleware to 5.3.4+ - High severity path traversal exposing developer files (Alerts 🚨 Security Alert Triage Report - 2025-10-25 #40, 🚨 Security Alert Triage Report - 2025-10-25 #39)
  4. Update body-parser to 1.20.3 - High severity DoS vulnerability (Alert #57)
  5. Monitor ip package - High severity SSRF with no patch available yet; avoid using isPublic() for security decisions (Alert Bump @angular-eslint/eslint-plugin-template from 15.2.1 to 20.5.0Β #43)
  6. Add workflow permissions - Add explicit permissions blocks to all GitHub Actions workflows (Alerts Bump loader-utils from 2.0.2 to 2.0.3Β #7, Add dependabot-copilot.yml workflow fileΒ #21, Bump azure/webapps-deploy from 2 to 3Β #23)
  7. Batch update remaining dev dependencies - Run npm audit fix to address 15 medium/low severity issues in development dependencies

Additional Context

Overall Risk Assessment: This repository's security posture is moderate. All vulnerabilities are in development dependencies (devDependencies in package.json), meaning they do not affect production deployments. However, they pose risks to:

  1. Developer machines - Path traversal and source code exposure vulnerabilities could compromise developer workstations
  2. Build pipeline integrity - Prototype pollution and code execution vulnerabilities could affect the build process
  3. Development server availability - DoS vulnerabilities could crash local development servers

Positive Findings:

  • No secrets exposed in the repository
  • No production dependency vulnerabilities
  • All code scanning alerts are configuration best practices, not code vulnerabilities

Recommendations:

  1. Implement automated dependency updates via Dependabot or Renovate
  2. Add workflow permission blocks as a template for all future workflows
  3. Consider using npm audit in CI/CD to prevent merging code with vulnerable dependencies
  4. Establish a policy to update dev dependencies quarterly
  5. For the ip package vulnerability (no patch): consider switching to an alternative IP validation library or implementing custom validation logic

Template Repository Note: This is marked as a template repository, so these vulnerabilities will be inherited by any repositories created from this template. Recommend fixing before users create new projects from this template.
