WordPress has released another update to its content management software, again calling it a “critical security release.” This is version 4.2.1, and here’s the important bit from the WordPress announcement:

WordPress 4.2.1 is now available. This is a critical security release for all previous versions and we strongly encourage you to update your sites immediately.

A few hours ago, the WordPress team was made aware of a cross-site scripting vulnerability, which could enable commenters to compromise a site. The vulnerability was discovered by Jouko Pynnönen.

Version 4.2.1 can be updated via your WordPress dashboard or by manual download. Some hosting services offer automatic upgrades that should be underway soon, if not already.
