A new version of WordPress is out and it's a SECURITY release, so we're urging everyone to have their websites upgraded as soon as possible.
WordPress 4.2.2 Security and Maintenance Release (wordpress.org)
WordPress 4.2.2 is now available. This is a critical security release for all previous versions and we strongly encourage you to update your sites immediately.
Version 4.2.2 addresses two security issues:
- The Genericons icon font package, which is used in a number of popular themes and plugins, contained an HTML file vulnerable to a cross-site scripting attack. All affected themes and plugins hosted on WordPress.org (including the Twenty Fifteen default theme) have been updated today by the WordPress security team to address this issue by removing this nonessential file. To help protect other Genericons usage, WordPress 4.2.2 proactively scans the wp-content directory for this HTML file and removes it. Reported by Robert Abela of Netsparker.
- WordPress versions 4.2 and earlier are affected by a critical cross-site scripting vulnerability, which could enable anonymous users to compromise a site. WordPress 4.2.2 includes a comprehensive fix for this issue. Reported separately by Rice Adu and Tong Shi.
The release also includes hardening for a potential cross-site scripting vulnerability when using the visual editor. This issue was reported by Mahadev Subedi.
Our Website Maintenance Department will be in contact with you regarding these upgrades. Clients that have signed up for our Automatic WordPress Update Program will get their website updated promptly.
Remember that you don't want to just update your WordPress core software but make sure all plugins and themes are up to date as well. Your plugins need to be updated weekly in order to keep your website in its best health / condition.
