- Exclude supabase/ from Docker build context (leaked service_role key file) - /api/files: exact per-user namespace match + reject path traversal; storage resolveKey rejects ".."/"." segments (fixes cross-user file read) - Add ownsProperty/Unit/Tenant checks to tenants, maintenance (landlord path), and documents (JSON branch, now field-whitelisted) create handlers - Escape user data in follow-up + payment-link emails (reuse escapeHtml) - Neutralize CSV formula injection in toCsv + export routes - Tighter sign-in rate limit (10/min); env-gated email verification + sender - Per-request nonce CSP; drop script-src 'unsafe-inline' (styles unchanged) - Add input length bounds; validate follow-ups POST body Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
