security: restrict CORS to explicit allowed origins#706
Merged
Conversation
- Replace wildcard origin:'*' with dynamic CORS_ORIGINS check - No CORS_ORIGINS env var = reject all cross-origin requests (secure default) - Add CORS_ORIGINS to Bindings interface - Add X-API-Key to allowed headers - Add CORS_ORIGINS=http://localhost:8787 to dev wrangler.toml configs - Same-origin requests (admin UI) are unaffected Breaking: cross-origin API consumers must be listed in CORS_ORIGINS Fixes VULN-003
Tests were sending Origin headers (localhost:3000, example.com) that don't match the CORS_ORIGINS allowlist. Updated to use http://localhost:8787 and assert the echoed origin instead of wildcard '*'.
