UUID Use Case

UUID CSRF Token

Cross-site request forgery tricks a logged-in browser into submitting a form. A per-session UUID token that only your page knows defeats it.

What Is UUID CSRF Token?

A CSRF token is a secret value your server issues and checks; an attacker's site cannot read it due to the same-origin policy.
A v4 UUID is unpredictable enough that an attacker cannot guess the valid token.

How to generate

Issue a v4 UUID token per session.
Render it in a hidden form field and a cookie.
On submit, require both to match (double-submit).

Use Cases

Banking transfer forms.
Profile update endpoints.
Admin actions.

Code Examples

JavaScript

const csrf = crypto.randomUUID();
session.csrf = csrf;
form.appendChild(hidden('csrf', csrf));

Frequently Asked Questions

Is a UUID strong enough for CSRF?

Yes — the attacker cannot read it from your page, so guessing a 122-bit random value is infeasible.

Double-submit vs synchroniser?

Double-submit (cookie + form) avoids server state; synchroniser token requires a server-side store.
