Root cause

State-changing requests rely on the session cookie the browser sends automatically; nothing verifies that the request came from the user’s own page.

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

1app.use(session({ cookie: { httpOnly: true } }));2app.post("/account/address", updateAddress);
