Cross-Site Request Forgery (CSRF) in pimcore/pimcore


Reported on

Dec 7th 2021


An attacker is able to log out a user if a logged-in user visits the attacker's website.

Proof of Concept

  <script>history.pushState('', '', '/')</script>
    <form action="">
      <input type="submit" value="Submit request" />


This vulnerability is capable of forging users to unintentional logout.

More details

One way GET could be abused here is that a person (competitor perhaps:) placed an image tag with src="<your logout link>" anywhere on the internet, and if a user of your site stumbles upon that page, he will be unknowingly logged out. This is why it should be a POST with a CSRF token.


While this cannot harm a user's account, it can be a great annoyance and is a valid CSRF.
