A critical cross-site-scripting (XSS) vulnerability of the WordPress core engine has been announced recently. The vulnerability affects all WordPress versions including the most recent major release (4.2) and has reportedly been fixed in minor security release 4.2.1.
That being said, we strongly recommend updating your WordPress scripts to the most recent version (4.2.1) as soon as possible. This version is already available for updating.
When performing the update, we recommend you follow WordPress script update instructions in the Official WordPress Codex at https://codex.wordpress.org/
