Upgrade Debian:unstable wordpress to version 3.4.2+dfsg-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream wordpress package and not the wordpress package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
The create_post function in wp-includes/class-wp-atom-server.php in WordPress before 3.4.2 does not perform a capability check, which allows remote authenticated users to bypass intended access restrictions and publish new posts by leveraging the Contributor role and using the Atom Publishing Protocol (aka AtomPub) feature.
