How to detect it

Nuclei template (active check)

Hotel Booking Management System - Information Disclosure via Health Endpoint

arnobt78 Hotel Booking Management System exposes GET /api/health/detailed without authentication, returning verbose runtime internals: OS platform and architecture, Node.js version, process PID, heap/RSS memory, CPU usage, and the MongoDB connection host and port. The fix gates /api/health/detailed behind verifyToken (JWT) and returns only coarse uptime/memory. This template requests the detailed health endpoint unauthenticated and confirms the leaked runtime fields are present in the response.

Name and description quoted from the template, written by VEDAS.

The template sends 1 request (GET /api/health/detailed); it decides using status, word matchers. Severity in the template: medium. Marked as not yet verified against a live vulnerable target.
