Weakness class (CWE)

CWE-287 · Improper Authentication

CVSS vector

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

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 class

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

Vulnerable

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

Fixed

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