Summary

Closes three CSRF security gaps identified in code review:

  • Added X-CSRF-Token and X-Workspace-Id to CORS allowed headers - Updated to accept CSRF token headers from frontend
  • Integrated CSRF token handling in web client - Added automatic token fetching, in-memory storage, inclusion in state-changing requests, and automatic refresh on 403 errors
  • Applied CSRF Guard globally - Added as in for application-wide protection

Test Plan

  • CSRF token fetching and caching works
  • X-CSRF-Token header included in POST/PUT/PATCH/DELETE requests
  • Automatic token refresh on 403 CSRF errors
  • @SkipCsrf() decorator works for exempted endpoints
  • All existing tests pass
  • Type checking passes
  • Linting passes

Changes

API (apps/api)

  • : Added X-CSRF-Token and X-Workspace-Id to CORS allowedHeaders
  • : Applied CsrfGuard globally as APP_GUARD

Web (apps/web)

  • : Added CSRF token management (fetch, store, include, refresh)
  • : Added comprehensive CSRF protection tests (35 total tests, all passing)

All tests passing. CSRF protection now enforced application-wide with automatic token management.
