Security updates are for everyone who use the wordpress at their CMS or blog management. If your blog is running an old version then it is vulnerable.

4) Delete all the files and folders of your wordpress directory.
5) Re Upload the fresh copy that you have just downloaded.
6) Run the database upgrade at wp-admin/upgrade.php.
7) Immediately change the password and set the strong one.
