Cross-Site Request Forgery (CSRF) is a web security vulnerability that allows an attacker to induce users to perform actions that they do not intend to perform

. The attack tricks the victim into submitting a malicious request, inheriting their identity and privileges to perform undesired actions

. CSRF attacks can lead to various consequences, such as changing the victim's email address, password, or making a funds transfer

. Some key aspects of CSRF attacks include:

  • Social Engineering : Attackers often use social engineering techniques, such as sending a link via email or chat, to trick users into executing actions on their behalf
  • State-Changing Requests : CSRF attacks target state-changing requests, such as changing the victim's email address or password
  • Anti-CSRF Measures : To prevent CSRF attacks, web applications can implement various defenses, such as CSRF tokens, which are unique, secret, and unpredictable values generated by the server-side application and shared with the client

To protect against CSRF attacks, it is essential to:

  1. Review code for CSRF vulnerabilities and ensure proper implementation of anti-CSRF measures
  1. Be cautious when clicking on links in emails or chats, as they may lead to malicious requests
  1. Implement strong authentication and authorization mechanisms to prevent unauthorized access and actions
