Cross-Site Request Forgery (CSRF) is a web security vulnerability that allows attackers to trick users into performing actions they did not intend to do on web applications where they are authenticated. This security flaw exploits the trust that a site has for the user’s browser, potentially leading to unauthorized commands being transmitted without the user’s knowledge.

At its core, CSRF involves an attacker inducing a victim to send a request to a web application on which the victim is authenticated with their credentials. This can result in unwanted actions, from changing email addresses to transferring funds, all without the user’s consent or knowledge.

CSRF attacks primarily rely on the presence of authentication cookies automatically sent with requests to a web app.

When a user is tricked into making a request (e.g., by clicking on a malicious link or loading an image), the browser includes these cookies…
