WordPress 2.2.1 – update/upgrade

Yesterday WordPress announced the immediate release of version 2.2.1 which besides fixing a few bugs also addresses several security issues which was discovered during the development process.

Unfortunately, 2.2.1 is not just a bug fix release. Some security issues came to light during 2.2.1 development, making 2.2.1 a required upgrade. 2.2.1 addresses the following vulnerabilities:

Remote shell injection in PHPMailer

Remote SQL injection in XML-RPC Discovered by Alexander Concha.

Unescaped attribute in default theme

So if you haven’t done it already, now would be a good time to upgrade. Visit the download section to grab the latest code.

Following the Detailed Upgrade Instructions I spent less than 30 minutes getting everything up and running. It might take a little longer if you’ve made changes to the core files, but all in all it shouldn’t take that long and it’s definitely worth it in the long run.

Please don’t hesitate to ask should you encounter any incompatibilities with some of my WordPress plugins or the Blogvaria WordPress theme.
