WordPress 4.0.1 has been released today and it is a important security release. So please update your WordPress site as soon as possible.
WordPress 4.0.1 is now available. This is a critical security release for all previous versions and we strongly encourage you to update your sites immediately.
Sites that support automatic background updates will be updated to WordPress 4.0.1 within the next few hours. If you are still on WordPress 3.9.2, 3.8.4, or 3.7.4, you will be updated to 3.9.3, 3.8.5, or 3.7.5 to keep everything secure. (We don’t support older versions, so please update to 4.0.1 for the latest and greatest.)
WordPress versions 3.9.2 and earlier are affected by a critical cross-site scripting vulnerability, which could enable anonymous users to compromise a site. This was reported by Jouko Pynnonen. This issue does not affect version 4.0, but version 4.0.1 does address these eight security issues:
- Three cross-site scripting issues that a contributor or author could use to compromise a site. Discovered by Jon Cave, Robert Chapin, and John Blackbourn of the WordPress security team.
- A cross-site request forgery that could be used to trick a user into changing their password.
- An issue that could lead to a denial of service when passwords are checked. Reported by Javier Nieto Arevalo and Andres Rojas Guerrero.
- Additional protections for server-side request forgery attacks when WordPress makes HTTP requests. Reported by Ben Bidner (vortfu).
- An extremely unlikely hash collision could allow a user’s account to be compromised, that also required that they haven’t logged in since 2008 (I wish I were kidding). Reported by David Anderson.
- WordPress now invalidates the links in a password reset email if the user remembers their password, logs in, and changes their email address. Reported separately by Momen Bassel, Tanoy Bose, and Bojan Slavkovi? of ManageWP.
Version 4.0.1 also fixes 23 bugs with 4.0, and we’ve made two hardening changes, including better validation of EXIF data we are extracting from uploaded photos. Reported by Chris Andrè Dale.

- Manage your media with style
Explore your uploads in a beautiful, endless grid. A new details preview makes viewing and editing any amount of media in sequence a snap.
- Working with embeds has never been easier
Paste in a YouTube URL on a new line, and watch it magically become an embedded video. Now try it with a tweet. Oh yeah – embedding has become a visual experience. The editor shows a true preview of your embedded content, saving you time and giving you confidence. You can now embed videos from CollegeHumor, playlists from YouTube, and talks from TED.
- Focus on your content
Writing and editing is smoother and more immersive with an editor that expands to fit your content as you write, and keeps the formatting tools available at all times.
- Finding the right plugin
There are more than 30,000 free and open source plugins in the WordPress plugin directory. WordPress 4.0 makes it easier to find the right one for your needs, with new metrics, improved search, and a more visual browsing experience.
WordPress 3.3 Beta 4 has been released!
With all our major tickets closed, we are very close to a release candidate. In Beta 4 we’ve fixed a bunch of bugs, cleaned up the UI, added real text in some of the screens that still had placeholder text in Beta 3 (post-update screen, the Dashboard welcome area, new feature pointers), and generally tightened things up. We updated to jQuery 1.7.1 and addressed a LOT of bugs.
WordPress 3.1.1 has been released.
This maintenance and security release fixes almost thirty issues in 3.1, including:
- Some security hardening to media uploads
- Performance improvements
- Fixes for IIS6 support
- Fixes for taxonomy and PATHINFO (/index.php/) permalinks
- Fixes for various query and taxonomy edge cases that caused some plugin compatibility issues
Version 3.1.1 also addresses three security issues discovered by WordPress core developers Jon Cave and Peter Westwood, of our security team. The first hardens CSRF prevention in the media uploader. The second avoids a PHP crash in certain environments when handling devilishly devised links in comments, and the third addresses an XSS flaw.
We suggest you update to 3.1.1 promptly. Download 3.1.1 or update automatically from the Dashboard ? Updates menu in your site’s admin area.
