DESCRIPTION:
A security issue has been reported in WordPress, which can be
exploited by malicious users to bypass certain security
restrictions.

The security issue is caused due to wp-admin/press-this.php script
not properly checking a user's permissions before publishing posts
and can be exploited by users without the "publish_posts"
permission.

Successful exploitation requires "Contributor-level" privileges.

The security issue is reported in versions prior to 3.1.2.

SOLUTION:
Update to version 3.1.2.

PROVIDED AND/OR DISCOVERED BY:
Andrew Nacin, WordPress.

The vendor also credits Benjamin Balter.
