WordPress is always on the path of continuous improvements by continuously testing the platform for any issues and fixing them so that the millions of WordPress blogs on the web can run efficiently and securely. The latest WordPress update released 3.0.5 as a security release. The release is very critical for the blogs with multiple user accounts with untrusted user account.
Reasons to upgrade to 3.0.5 immediately :
- 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.
