Overview
Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they're currently authenticated.
CSRF attacks specifically target state-changing requests, not theft窃取 of data, since the attacker has no way to see the response to the forged伪造的 request.
With a little help of social engineering (such as sending a link via email or chat), an attacker may trick the users of a web application into executing actions of the attacker's choosing.
If the victim is a normal user, a successful CSRF attack can force the user to perform state changing requests like transferring funds, changing their email address, and so forth.
If the victim is an administrative account, CSRF can compromise(因行为不当)使陷入危险 the entire web application.
