A CSRF attack takes advantage of user identity by creating confusion. It typically tricks the user with a transaction activity in which the state gets changed—for example, changing the password of a shopping website or requesting a money transfer to your bank.
It is slightly different than an XSS attack as, with CSRF, the attacker tries to forge the request rather than insert a code script. For example, the attacker can forge a request to transfer a certain amount of money from the user's bank and send that link in an email to the user. As soon as users click on that link, the bank gets a request and transfers the money to the attacker's account. CSRF has minimal impact on the individual user account, but it can be very harmful if attackers are able to get into the admin account.
