WordPress 4.3.1 Security and Maintenance Release.
WordPress 4.3.1 was released on the 15th September 2015. This is a security release for all previous versions and WordPress strongly encourage you to update your sites immediately.
This important release addresses three issues, including two cross-site scripting vulnerabilities and a potential privilege escalation that could be used to compromise your website.
It is important that you update your site as soon as possible in order to maintain best levels of security and protection for your website.
If you already had the previous version of WordPress installed, this new update should install automatically and your site administrator should have received an email informing of this.
If you haven’t updated for a while and are running an older version of WordPress, you will need to manually update it.
