WordPress 3.0.5
Posted February 7, 2011 by Andrew Nacin

WordPress 3.0.5 is now available and is a security hardening update for all previous WordPress versions.

This security release is required if you have any untrusted user accounts, but it also comes with important security enhancements and hardening. All WordPress users are strongly encouraged to update.

The release addresses a number of issues and provides two additional enhancements:

Two moderate security issues were fixed that could have allowed a Contributor- or Author-level user to gain further access to the site.

One information disclosure issue was addressed that could have allowed an Author-level user to view contents of posts they should not be able to see, such as draft or private posts.

Two security enhancements were added. One improved the security of any plugins which were not properly leveraging our security API. The other offers additional defense in depth against a vulnerability that was fixed in previous release.

Thanks to Nils Jueneman and Saddy for their private and responsible disclosures to This e-mail address is being protected from spambots. You need JavaScript enabled to view it for two of the issues. The others were reported or repaired by our security team.

Download 3.0.5 or update automatically from the Dashboard > Updates menu in your site’s admin area. Please update immediately.
