Root cause

Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

1app.use("/admin", requireSession, adminRouter);2
3// Route added later skips the middleware4app.post("/admin-api/config", updateConfig);

1const admin = express.Router();2admin.use(requireSession, requireRole("admin"));3
4admin.post("/config", updateConfig);5app.use("/admin", admin);
