shadowdao 7ba91d9829 fix(builder): sanitize non-string style values + allowlist element tags (XSS)
Adversarial re-review found the C1 fix incomplete plus an adjacent
same-class XSS, both reachable via the AI update_props path and
deserialized saved state:

- cssPropsToString only ran sanitizeCssValue on typeof-string values, so a
  non-string style value (array/object) with a valid key skipped
  sanitization entirely and was template-coerced raw into style="...",
  e.g. { color: ['red', '"><img src=x onerror=alert(1)>'] }. Now every
  non-number value is coerced with String() and sanitized; numbers stay
  raw. sanitizeBreakoutChars also now escapes < and > (previously only ;
  and ") as defense-in-depth, since values can reach it from non-string
  sources.

- props.tag (Container) and props.level (Heading) were interpolated raw
  into the tag position of exported HTML (`<${tag}`, `<${level}`) with no
  runtime validation, letting a malicious value break out of the tag
  entirely. Both are now allowlisted/clamped against their known-safe sets
  (div/section/article/header/footer/main; h1-h6), falling back to
  div/h2. Applied in Container's live render + toHtml, Heading's live
  render + toHtml, and the typeName==='div' fallback branch in
  html-export.ts's renderNode (hit for unresolved/legacy node types).

WHP Site Builder v2

A visual drag-and-drop website builder for WHP, rebuilt from the ground up with Craft.js, React 18, and TypeScript. Replaces the legacy GrapesJS-based editor.

Quick Start

npm install
npm run dev

Opens at http://localhost:5173. The editor runs in standalone mode without WHP integration.

Build and Deploy

# Build production bundle
npm run build

# Deploy to WHP
cp dist/index.html /docker/whp/web/site-builder/editor.html
cp -r dist/js/ /docker/whp/web/site-builder/js/
cp -r dist/css/ /docker/whp/web/site-builder/css/

The PHP wrapper (index.php) injects WHP_CONFIG (user session, CSRF token, site ID) into the HTML before serving.

Architecture

  • Craft.js - React-based visual editor framework (no iframe, direct DOM rendering)
  • Inline styles - All user content uses React CSSProperties, no class-based CSS
  • Component pattern - Each component is a self-contained file with: render logic, settings panel, Craft.js config, and HTML export method
  • 3-panel layout - Left (blocks/pages/layers/assets), Center (canvas with device preview), Right (styles/settings/head)
  • Dark theme - CSS custom properties, Inter font, blue accent

Components (22)

Category Components
Layout Container, Section, ColumnLayout (1-6 cols), BackgroundSection, HeaderZone, FooterZone
Basic Heading (H1-H6), TextBlock, ButtonLink, Navbar, Footer, Divider, Spacer
