On January 16, 2017 the WordPress 4.9.2 update was released, which included several security updates, as well as bug fixes for all versions after WordPress 3.7. WordPress has reported that a cross-site scripting (XSS) vulnerability was found in a group of files used to play Flash videos, which was included with all WordPress versions after 3.7. However, because most browsers no longer require these files to play video content, upgrading to WordPress 4.9.2 removes these files. Due to the nature of XSS vulnerabilities, it is highly recommended that WordPress users update their websites immediately to avoid possible compromise.
WordPress notes the following bug fixes and features in particular:
SMART PLUS, SiteLock INFINITY, and Patchman users are protected from this security issue, as SMART/PATCH and the Patchman libraries have been updated with secure patches that protect plugins and themes reliant on their current versions. It is still advised that website owners plan full version upgrades as soon as possible to take advantage of the new features and full list of bug fixes in WordPress 4.9.2.
