DESCRIPTION:
Charlie Eriksen has discovered a vulnerability in the FourSquare
Checkins plugin for WordPress, which can be exploited by malicious
people to conduct cross-site request forgery attacks.

The application allows users to perform certain actions via HTTP
requests without performing proper validity checks to verify the
requests. This can be exploited to e.g. insert malicious script when
a logged-in user visits a specially crafted web page.

The vulnerability is confirmed in version 1.2. Prior versions may
also be affected.

SOLUTION:
Update to version 1.3.

PROVIDED AND/OR DISCOVERED BY:
Charlie Eriksen via Secunia.
