Bear in mind, by solely using this middleware, we can't guarantee your app will be free from CSRF attacks. Refer to [CSRF Prevention Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/Cross-Site_Request_Forgery_Prevention_Cheat_Sheet.html) and [pillarjs/understanding-csrf](https://github.com/pillarjs/understanding-csrf) for more details.
