How missing authorization enforcement happens in Node.js Express routers and how to fix it

A critical authorization bypass was discovered in lib/router.js where readOnly and noDelete configuration options were only enforced through UI controls, not server-side middleware. Any authenticated user could bypass these restrictions by sending direct HTTP requests to perform destructive operations like database deletion or document modification. The fix adds Express middleware that enforces these security modes at the server level, blocking POST, PUT, and DELETE requests when appropriate.
