WordPress, one of the better blog systems out there (so good that we at Let’s Learn IT are using it ourselves ), and probably the only blog system that you’ll have up and running on your server in 5 minutes or less, have upgraded their software to version 2.8.6.

The latest version can be downloaded from their site, and contains the following changes:

WordPress 2.8.6 Security Release

2.8.6 fixes two security problems that can be exploited by registered, logged in users who have posting privileges. If you have untrusted authors on your blog, upgrading to 2.8.6 is recommended.

The first problem is an XSS vulnerability in Press This discovered by Benjamin Flesch. The second problem, discovered by Dawid Golunski, is an issue with sanitizing uploaded file names that can be exploited in certain Apache configurations. Thanks to Benjamin and Dawid for finding and reporting these.
