What's New in WordPress 4.7.1
Security
- Remote code execution (RCE) in PHPMailer – No specific issue appears to affect WordPress or any of the major plugins we investigated but, out of an abundance of caution, we updated PHPMailer in this release. This issue was reported to PHPMailer by Dawid Golunski and Paul Buonopane.
