WordPress 4.2.2 is now available. This is a critical security release for all previous versions and we strongly encourage you to update your sites immediately.
- The Genericons icon font package, which is used in a number of popular themes and plugins, contained an HTML file vulnerable to a cross-site scripting attack. All affected themes and plugins hosted on WordPress.org (including the Twenty Fifteen default theme) have been updated today by the WordPress security team to address this issue by removing this nonessential file. To help protect other Genericons usage, WordPress 4.2.2 proactively scans the wp-content directory for this HTML file and removes it. Reported by Robert Abela of Netsparker.
- WordPress versions 4.2 and earlier are affected by a critical cross-site scripting vulnerability, which could enable anonymous users to compromise a site. WordPress 4.2.2 includes a comprehensive fix for this issue. Reported separately by Rice Adu and Tong Shi.
The release also includes hardening for a potential cross-site scripting vulnerability when using the visual editor.

WordPress Updating Tips
When updating WordPress themes or plugins following the simple steps below can save you some headaches. With full revision updates (for example: 3.x to 4.0): Doing a quick double-check with theme and plugin developers *before* updating to see if they have any concerns or comments about your theme and the new version is wise. If you are using quality a theme and plugins the developer(s) will be on top of this.
Step-by-step instructions to help you safely and easily update to the most recent version of WordPress.
Before you update we need to do a little housekeeping:
- Save your WordPress XML file to your hard drive. You do this by clicking on the Tools icon in the left sidebar and then Export. On the next screen click on Download Export File. You might want to create a new Folder on your hard drive where you keep all your Website files. Name it WP Backup so you know to save all backup files for WP there (and you’ll know where to find them if you need them). It is a good idea to back up this file once a month anyway regardless if an update is needed.
- Backup your WordPress database. There is a nifty plugin that makes this process a no-brainer, WP-DBManager. This plugin is also a must have for repairing and optimizing your database (which you should be doing minimally monthly to keep things running smoothly).
- FTP into your Web hosting server and download a copy of your database bakcup so you have a copy off your server. That backup won’t do you any good if the server crashes or has issues. Even better, store the backup file in the cloud or on an external drive in case you have computer problems.
- Cover all the bases and download your theme/framework/child theme folders to your local hard drive. This is just good practice if you have customized any theme files.
- Then, to be safe, deactivate all plugins before upgrading.
It is a good idea to review my article:
WordPress How To: Do the Mother of All Backups
Once you get the above tasks accomplished, follow the links in the nag bar (it’s called a nag because that yellow bar will be up there “nagging” you until you take care of the important issue noted) and update your site to the latest version of WordPress.
Then, don’t forget to reactivate and update your plugins. You’ll see with each WordPress update that plugin developers also update their plugins which you can also do with one click. You’ll see the now familiar yellow nag bar under the plugin name in the plugins area with a link to “upgrade automatically.”
If you find after an update that something is not working as it was, go through the systematic process of deactivating your plugins one at a time until you find the culprit. If the developer has not updated his/her plugin to work with the lasted update, find another plugin whose developer is on top of these things.
Updating should not be ignored or put off. When you keep up with WordPress, have a Premium Theme and Plugin updates, you are not only keeping up with technology, but you make sure your site is secure and functioning error free.
