WordPRess 4.3.1 is now available. This is a security release and we strongly encourage all customers to upgrade as soon as possible.
Three main issues were addressed in this release:
- 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).
Full details can be found on the WordPress blog post.
