WordPress 4.3.1 is now available for download and upgrade.
This is a security release for all previous versions and we strongly encourage you to update your sites immediately.
WordPress 4.3.1 addresses three issues, including two cross-site scripting vulnerabilities and a potential privilege escalation.
- WordPress versions 4.3 and earlier are vulnerable to a cross-site scripting vulnerability when processing shortcode tags (CVE-2015-5714).
- A separate cross-site scripting vulnerability was found in the user list table.
- Finally, in certain cases, users without proper permissions could publish private posts and make them sticky (CVE-2015-5715).
Download WordPress 4.3.1 or venture over to Dashboard → Updates and simply click “Update Now.” Sites that support automatic background updates are already beginning to update to WordPress 4.3.1.
