## AI overview

This tutorial explains cross-site request forgery (CSRF) attacks against Node.js applications. It describes how attackers exploit trust in authenticated browser sessions, session IDs, and cookies to trigger unauthorized actions, then introduces practical protection methods, testing approaches, code examples, and security best practices.

## Source excerpt

Victor Ikechukwu October 17, 2023 A cross-site request forgery attack (CSRF) attack is a security vulnerability capitalizing on trust between a web browser and a legitimate website. Crafty attackers manipulate browsers into executing malicious actions on websites where users authenticate themselves and log in. Often, these attacks start when users click a link attached to a deceptive email or land on a compromised website, unaware of the logic executing in the background.
