After the success we’ve had with new branch releases of the past few WordPress branches (2.6 and 2.7 both come to mind), it is a little surprising to see that we already have yet another security patch, this time being WordPress 2.8.3.  Because this is a security update, it is highly recommended that everyone take a moment to upgrade their WordPress installation.

Here is what the WordPress team had to say about the WordPress 2.8.3 security update:

Unfortunately, I missed some places when fixing the privilege escalation issues for 2.8.1.  Luckily, the entire WordPress community has our backs.  Several folks in the community dug deeper and discovered areas that were overlooked.  With their help, the remaining issues are fixed in 2.8.3.  Since this is a security release, upgrading is highly recommended.  Download 2.8.3, or upgrade automatically from your admin.

The ribbon reminder in your dashboard just showed up, so you can now do your automatic upgrade, or manually download WordPress 2.8.3 from here.

Although it isn’t very long after WordPress 2.8.1 was released, WordPress 2.8.2 was just released today and is a security update which corrects a XSS vulnerability which was discovered.   Comment author URLs were not fully sanitized when displayed in the admin. This could be exploited to redirect you away from the admin to another site.

Due to this being a security update, it is strongly recommended that you upgrade your WordPress 2.8 installations as soon as possible.  This can quickly and easily be done via your WordPress administrator panel (for WordPress 2.7 and newer installations) via Tools –> Upgrade, or you can manually download it here.
