FUXA provides guest and invalid-token access to protected read APIs in secure mode

Summary

When secureEnabled=true, FUXA 1.3.0-2773 still allows guest and invalid-token requests to read project, alarms, and scheduler APIs.

Details

In secure mode, requests with no token or an explicitly invalid token were still able to access protected read endpoints.

Confirmed behavior:

• guest GET /api/project returned 200 OK
• invalid-token requests to /api/project also returned successful responses containing project data
• guest and invalid-token requests also returned 200 OK on:
  • /api/alarms
  • /api/scheduler

Relevant code paths identified during analysis:

• server/api/jwt-helper.js
  • verifyToken() converts missing-token or invalid-token states into guest context instead of rejecting the request
• server/api/projects/index.js
• server/api/alarms/index.js
• server/api/scheduler/index.js

These handlers accepted the guest context and returned sensitive data in secure mode.

PoC

Tested only against isolated local lab instances under the original tester's control. No production, customer, shared, or third-party systems were involved.

Reproduction:

1. Start FUXA 1.3.0-2773.
2. Set secureEnabled=true.
3. Send unauthenticated requests to:
   • GET /api/project
   • GET /api/alarms
   • GET /api/scheduler?id=test
4. Observe 200 OK responses.
5. Send the same requests with an explicitly invalid x-access-token value.
6. Observe the same successful responses.

The exact HTTP requests and local PoC script used for confirmation can be provided upon request.
