Weakness class (CWE)
CWE-287 · Improper AuthenticationCVSS vector
AV:N/AC:L/Au:N/C:P/I:P/A:P
nvd-primary
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.
The bug in code
The whole CWE-287 classA representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

// Route added later skips the middlewareapp.post("/admin-api/config", updateConfig);Fixed
