WordPress Site Owners – Update Now

WordPresslogoJust a quick note to my WordPress pals – the latest update, WordPress 4.2.3, has an import fix for a cross site scripting (XSS) vulnerability that leaves your site vulnerable to attack.  According to Sophos:

“The flaw allows WordPress users who have Contributor or Author roles to add javascript to a site (something normally reserved for Editors and Administrators) using specially crafted shortcodes.

Attackers who can add javascript to a site can use it to do all manner of damage such as infecting users with malware or stealing their cookies.”

This is something we can do without, so my advise is to update today.
