DESCRIPTION:
Ivano Binetti has discovered a vulnerability in Contao, which can be
exploited by malicious people to conduct cross-site request forgery
attacks.

The vulnerability is caused due to the application allowing users to
perform certain actions via HTTP requests without performing proper
validity checks to verify the requests. This can be exploited to e.g.
delete a user, delete news, or delete a newsletter when a logged-in
administrative user visits a specially crafted web page.

The vulnerability is confirmed in version 2.11.0. Other versions may
also be affected.

SOLUTION:
Do not browse untrusted websites or follow untrusted links while
logged in to the application.
