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).

Each component defined a .craft.related.settings panel that was never
rendered -- the right panel renders only GuidedStyles (per-type
*StylePanel components), never .related.settings. Removed all dead
settings components across every component, their settings-only helpers
(including the dead uploadToWhp/showBrowser/handleBrowse asset-browse
blocks in Logo/Navbar/VideoBlock/FeaturesGrid, and CtasEditor in
_cta-helpers), and dropped the now-empty related keys. Render output,
.craft props/rules, and toHtml statics are unchanged.

Rebuilt the visual site builder from scratch using Craft.js, React 18,
and TypeScript. The new editor renders directly in the DOM (no iframe),
supports 40+ components, multi-page with shared header/footer, 16
templates, full-spectrum color/gradient controls, custom head code
injection, save/publish workflow, and auto-save.
