WordPress 3.8.2 is now available. This is an important security release for all previous versions and we strongly encourage you to update your sites immediately.
This releases fixes a weakness that could let an attacker force their way into your site by forging authentication cookies. This was discovered and fixed by Jon Cave of the WordPress security team.
It also contains a fix to prevent a user with the Contributor role from improperly publishing posts. Reported by edik.
This release also fixes nine bugs and contains three other security hardening changes:
- Pass along additional information when processing pingbacks to help hosts identify potentially abusive requests.
- Fix a low-impact SQL injection by trusted users. Reported by Tom Adams of dxw.
- Prevent possible cross-domain scripting through Plupload, the third-party library WordPress uses for uploading files. Reported by Szymon Gruszecki.
Download WordPress 3.8.2 or venture over to Dashboard â†’ Updates and simply click “Update Now.”
Sites that support automatic background updates will be updated to WordPress 3.8.2 within 12 hours. If you are still on WordPress 3.7.1, you will be updated to 3.7.2, which contains the same security fixes as 3.8.2. We don’t support older versions, so please update to 3.8.2 for the latest and greatest.
Or Try the Also Secure WordPress 3.9 Release Candidate
As teased earlier, the first release candidate for WordPress 3.9 is now available for testing!
We hope to ship WordPress 3.9 next week, but we need your help to get there. If you haven’t tested 3.9 yet, there’s no time like the present. (Please, not on a production site, unless you’re adventurous.)
To test WordPress 3.9 RC1, try the WordPress Beta Tester plugin (you’ll want “bleeding edge nightlies”). Or you can download the release candidate here (zip). If you’d like to learn more about what’s new in WordPress 3.9, visit the work-in-progress About screen in your dashboard ( â†’ About in the toolbar) and check out the Beta 1 post.
If you’re a plugin author, there are two important changes in particular to be aware of:
- TinyMCE received a major update, to version 4.0. Any editor plugins written for TinyMCE 3.x might require some updates. (If things broke, we’d like to hear about them so we can make adjustments.) For more, see TinyMCE’s migration guide and API documentation, and the notes on the core development blog.
- WordPress 3.9 now uses the MySQLi Improved extension for sites running PHP 5.5. Any plugins that made direct calls to
mysql_*functions will experience some problems on these sites. For more information, see the notes on the core development blog.
Be sure to follow along the core development blog, where we will be continuing to post notes for developers for 3.9. (For example, read this if you are using Masonry in your theme.) And please, please update your plugin’s Tested up to version in the readme to 3.9 before April 16.
This haiku’s the easy one
3.9 is near
