Code Review: fix-dashboard-cors-origin

Reviewed Files

  • automaton/dashboard/ui/app.py (SECURITY_HEADERS, _send_json(), _send_error(), do_OPTIONS())
  • tests/test_app.py

Changes

Removed wildcard CORS headers (Access-Control-Allow-Origin: *), replaced with security headers (X-Content-Type-Options: nosniff, X-Frame-Options: DENY).

Analysis

  • Security: Removing wildcard CORS eliminates the risk of cross-origin attacks from malicious local web pages
  • Single-origin app: The dashboard is a local web app served from a single origin — CORS is unnecessary
  • Security headers: X-Content-Type-Options: nosniff prevents MIME type sniffing, X-Frame-Options: DENY prevents clickjacking
  • OPTIONS handler: do_OPTIONS() still returns 204 No Content (for preflight requests) but without CORS headers
  • Tests: Test assertions correctly verify absence of CORS headers and presence of security headers

Verdict: PASS

The fix eliminates a security vulnerability while adding useful hardening headers. Tests are properly updated.
