Summary

  • allow blob: in frame-src for the Next canvas CSP so PDF Blob iframe previews are not blocked
  • allow blob: in frame-src for the Go tenant wrapper CSP so multiple CSP headers do not intersect-block the preview
  • add CSP regression tests for both layers

Tests

  • npm test -- csp-nonce.test.ts AttachmentPDF.test.tsx
  • npm run build
  • go test ./internal/middleware -run 'TestSecurityHeaders|TestCSPCanvasRoutesGetPermissivePolicy' -count=1
