Week 12: Security Hardening 🔒

Date: November 28, 2025
Duration: 2 hours
Status: ✅ COMPLETE

Overview

Addressed 13 security vulnerabilities detected by GitHub Dependabot through systematic analysis, testing, and documentation. Fixed all production-critical issues while accepting documented dev-only risks.

Results

GitHub Verification: Dependabot scan confirms vulnerability reduction from 13 → 4 (69% reduction)

Metric Before After Improvement
Total Vulnerabilities 13 4 -9 (69%) ✅
High Severity 5 1 -4 (80%) ✅
Moderate Severity 8 3 -5 (63%) ✅
Production-Affecting 3 0 -3 (100%) ✅

Vulnerabilities Fixed ✅

Backend (Production-Critical):

  • validator.js: 13.15.23 (URL validation bypass)
  • body-parser: 2.2.1 (DoS vulnerability)
  • glob: 10.5.0 (command injection)

Frontend (Development):

  • glob: 10.5.0 (command injection)
  • js-yaml: 4.1.1 (prototype pollution)
  • node-forge: 1.3.2 (ASN.1 vulnerabilities)

Remaining Vulnerabilities (Accepted) ⚠️

4 dev-only vulnerabilities locked in react-scripts@5.0.1:

  • nth-check, css-select, svgo, postcss
  • Production Impact: None (dev-only, not included in production build)
  • Justification: Fixing requires breaking changes that would destroy application
  • Documentation: Full analysis in SECURITY_UPDATE_LOG.md

Testing Performed

  • ✅ Backend server verified operational (48 API endpoints)
  • ✅ Frontend production build successful (135.42 kB JS)
  • ✅ Authentication tested (JWT token generation)
  • ✅ Database connections verified
  • ✅ No breaking changes introduced

Git History

  • 856cf64: Backend security fixes
  • f859467: Frontend security fixes
  • 033b392: Comprehensive documentation
  • 42f9234: Test checklist update
  • Tag: v1.0-security-hardened

Full Documentation: SECURITY_UPDATE_LOG.md (7.6KB, 226 lines)

Known Issues & Limitations

Hardcoded Values

1. COOP_COURSE_ID = 57 (backend/routes/faculty.js lines 1125, backend/routes/student.js line 410)

  • Reason: Week 9 fix for co-op timeline calculator - course code mismatch ('COOP' vs 'CO-OP')
  • Impact: System depends on CO-OP course existing with exact ID 57
  • Mitigation: Utility script backend/utils/createCoopCourse.js ensures course exists
  • Alternative Considered: Dynamic lookup via Course.findOne({where: {code: 'CO-OP'}}) but hardcoding more reliable for critical system course
  • Evidence: reference_document/DegreeAdmin - Week 9 Development Log.md lines 75-169

2. Current Academic Year = 2024 (backend/routes/faculty.js line 78)

  • Location: GET /api/faculty/advisees filters current semester schedules by year: 2024
  • Impact: Will need annual update for accuracy

3. Faculty Advisor Capacity = 10 advisees (backend/routes/admin.js line 1510)

  • Location: POST /api/admin/assignments enforces maximum
  • Reason: Requirement for manageable advising load
  • Impact: Cannot assign more than 10 students per faculty

Security Considerations (Week 12)

Production Security: ✅ EXCELLENT

  • 0 production vulnerabilities in backend
  • 0 production vulnerabilities in frontend
  • All critical/high-severity production issues resolved

Development Security: ⚠️ ACCEPTABLE

  • 4 dev-only vulnerabilities in react-scripts dependency chain
  • No production exposure (webpack-dev-server, postcss, svgo not deployed)
  • Risk accepted with comprehensive documentation

Mitigation:

  • Regular Dependabot monitoring
  • Production builds exclude all dev dependencies
  • Dev environment localhost-only access
  • Future migration to Vite or Next.js considered
