4.7.1 Release Candidate

A Release Candidate for WordPress 4.7.1 is now available. This security and maintenance release fixes 62 issues reported against 4.7 and is scheduled for final release on Wednesday, January 11, 2017. Note this does not address a number of other issues, which are slated for a 4.7.2 release.

Thus far WordPress 4.7 has been downloaded over 9 million times since its release on December 6, 2016. Please help us by testing this release candidate to ensure 4.7.1 fixes the reported issues and doesn’t introduce any new ones. As always, the entire WordPress project is grateful to security reporters for practicing responsible disclosure.

PHPMailer Update

Last month a security vulnerability (CVE 20016-10033) in the PHPMailer library was made public. WordPress uses this library as the basis for its email functionality. The Security Team has spent some time analysing this vulnerability, and how it applies to WordPress. This vulnerability does not appear to be directly exploitable in WordPress Core, or any major plugins in the plugin directory. The wp_mail() function, which WordPress Core and most plugins use for sending email, blocks this vulnerability from being exploited.
