This vulnerability makes it possible for an attacker to update arbitrary site options on a vulnerable site, provided they could trick a site's administrator into performing an action, such as clicking on a link.  


Cross-site request forgery occurs when an authenticated end-user is tricked by an attacker into submitting a specially crafted web request. CSRF can compromise the entire web application if the victim account is an administrator account.  


  • Taking full control over authenticated end-user’s account. 
  • Taking control of the entire web application. 
  • Sensitive information exposure.
