DESCRIPTION:
A vulnerability has been discovered in Plone, 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 any
validity checks to verify the request. This can be exploited to
create new users or change privileges given to various groups by
tricking an administrator into opening a malicious web page.

The vulnerability is confirmed in version 3.0.6 and reported in all
previous versions.

SOLUTION:
Do not browse untrusted websites while logged on to Plone.
