Cycle 4 (2025-12-23)

Items Addressed: DEBT-06

Summary:

  • DEBT-06: Implemented comprehensive security headers in staticwebapp.config.json:
    • Enhanced CSP with frame-ancestors 'none', base-uri 'self', form-action 'self'
    • Added strict-transport-security with 1-year max-age, includeSubDomains, and preload
    • Added x-content-type-options: nosniff to prevent MIME sniffing
    • Added x-frame-options: DENY for clickjacking protection
    • Added x-xss-protection: 1; mode=block as legacy XSS defense
    • Added referrer-policy: strict-origin-when-cross-origin for privacy
    • Added permissions-policy restricting unused browser APIs (camera, microphone, geolocation, etc.)

Note: unsafe-inline for styles remains necessary because Tailwind CSS in static exports (output: 'export') cannot use nonce-based CSP without server-side rendering. This is a known limitation documented in the Tailwind CSS and Next.js communities.

Files Modified:

  • public/staticwebapp.config.json - Comprehensive security headers

Remaining after Cycle 4: 0 items ✅
