WordPress 3.5.1 Maintenance and Security Release

WordPress 3.5.1 is now available. Version 3.5.1 is the first maintenance release of 3.5, fixing 37 bugs. It is also a security release for all previous WordPress versions. For a full list of changes, consult the list of tickets and the changelog, which include:

  • Editor: Prevent certain HTML elements from being unexpectedly removed or modified in rare cases.
  • Media: Fix a collection of minor workflow and compatibility issues in the new media manager.
  • Networks: Suggest proper rewrite rules when creating a new network.
  • Prevent scheduled posts from being stripped of certain HTML, such as video embeds, when they are published.
  • Work around some misconfigurations that may have caused some JavaScript in the WordPress admin area to fail.
  • Suppress some warnings that could occur when a plugin misused the database or user APIs.

Additionally, a bug affecting Windows servers running IIS can prevent updating from 3.5 to 3.5.1. If you receive the error “Destination directory for file streaming does not exist or is not writable,” you will need to follow the steps outlined on the Codex.

WordPress 3.5.1 also addresses the following security issues:

  • A server-side request forgery vulnerability and remote port scanning using pingbacks. This vulnerability, which could potentially be used to expose information and compromise a site, affects all previous WordPress versions. This was fixed by the WordPress security team. We’d like to thank security researchers Gennady Kovshenin and Ryan Dewhurst for reviewing our work.
  • Two instances of cross-site scripting via shortcodes and post content. These issues were discovered by Jon Cave of the WordPress security team.
  • A cross-site scripting vulnerability in the external library Plupload. Thanks to the Moxiecode team for working with us on this, and for releasing Plupload 1.5.5 to address this issue.

WordPress 3.3.2 (and WordPress 3.4 Beta 3)

WordPress 3.3.2 is available now and is a security update for all previous versions.

Three external libraries included in WordPress received security updates:

  • Plupload (version 1.5.4), which WordPress uses for uploading media.
  • SWFUpload, which WordPress previously used for uploading media, and may still be in use by plugins.
  • SWFObject, which WordPress previously used to embed Flash content, and may still be in use by plugins and themes.

Thanks to Neal Poole and Nathan Partlan for responsibly disclosing the bugs in Plupload and SWFUpload, and Szymon Gruszecki for a separate bug in SWFUpload.

WordPress 3.3.2 also addresses:

  • Limited privilege escalation where a site administrator could deactivate network-wide plugins when running a WordPress network under particular circumstances, disclosed by Jon Cave of our WordPress core security team, and Adam Backstrom.
  • Cross-site scripting vulnerability when making URLs clickable, by Jon Cave.
  • Cross-site scripting vulnerabilities in redirects after posting comments in older browsers, and when filtering URLs. Thanks to Mauro Gentile for responsibly disclosing these issues to the security team.

These issues were fixed by the WordPress core security team. Five other bugs were also fixed in version 3.3.2. Consult the change log for more details.

WordPress 3.4 Beta 3 also available

Our development of WordPress 3.4 development continues. Today we are proud to release Beta 3 for testing. Nearly 90 changes have been made since Beta 2, released 9 days ago. (We are aiming for a beta every week.)

This is still beta software, so we don’t recommend that you use it on production sites. But if you’re a plugin developer, a theme developer, or a site administrator, you should be running this on your test environments and reporting any bugs you find. (See the known issues here.) If you’re a WordPress user who wants to open your presents early, take advantage of WordPress’s famous 5-minute install and spin up a secondary test site. Let us know what you think!

Version 3.4 Beta 3 includes all of the fixes included in version 3.3.2. Download WordPress 3.4 Beta 3 or use the WordPress Beta Tester plugin.
