XSS Vulnerability In WordPress – Update Now

The guys from WordPress just released version 4.2.3 of their software, which is mostly a security update. They “strongly encourage you to update your sites immediately.“ To do so just visit your Dashboard, click on ‘Updates’ and then on ‘Update Now’. As mentioned above you’ll only have to update manually if, for whatever reason, you decided to disable the automatic updates.

According to their blog entry the newest version contains fixes for 20 bugs from 4.2. The page also says: “WordPress versions 4.2.2 and earlier are affected by a cross-site scripting vulnerability, which could allow users with the Contributor or Author role to compromise a site. This was initially reported by Jon Cave and fixed by Robert Chapin, both of the WordPress security team, and later reported by Jouko Pynnönen.

We also fixed an issue where it was possible for a user with Subscriber permissions to create a draft through Quick Draft. Reported by Netanel Rubin from Check Point Software Technologies.“

And don’t forget: Since WordPress is definitely one of the most popular Content Management Systems and blogging platforms out there it remains an attractive target for cybercriminals – especially due to the huge user base. Administrators should always keep their WordPress installations (including addons and themes) updated and patch as soon as there are security updates available.
