WordPress 4.6.1 is now available. This is a security release for all previous versions and we strongly encourage you to update your sites immediately.

WordPress versions 4.6 and earlier are affected by two security issues: a cross-site scripting vulnerability via image filename, reported by SumOfPwn researcher Cengiz Han Sahin; and a path traversal vulnerability in the upgrade package uploader, reported by Dominik Schilling from the WordPress security team.
