WordPress 2.3.2 has just been released, and it contains critical updates that fix some vulnerabilities in how WordPress creates Draft entries. Anyone using the WordPress 2.3.x line should immediately go to WordPress.org and download the new version. Unless you’ve done something strange to your core files all you need to do is overwrite your current install with the new version to successfully upgrade–then go to wp-admin/upgrade.php in your web browser to finalize the database update.
