WordPress 4.7.1 Security & Maintenance Release – Upgrade ASAP!
The latest release of WordPress is 4.7.1. This update is a Security + Maintenance update.
With security issues and 62 bug fixes, this update is a ‘must have’.
If you haven’t applied this update, contact your webmaster and have them do it. If you don’t have a webmaster – call us for WordPress Maintenance!!
WordPress versions 4.7 and earlier are affected by eight security issues:
- 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.
- The REST API exposed user data for all users who had authored a post of a public post type. WordPress 4.7.1 limits this to only post types which have specified that they should be shown within the REST API. Reported by Krogsgard and Chris Jean.
- Cross-site scripting (XSS) via the plugin name or version header on
update-core.php. Reported by Dominik Schilling of the WordPress Security Team.
- Cross-site request forgery (CSRF) bypass via uploading a Flash file. Reported by Abdullah Hussam.
- Cross-site scripting (XSS) via theme name fallback. Reported by Mehmet Ince.
- Post via email checks
mail.example.comif default settings aren’t changed. Reported by John Blackbourn of the WordPress Security Team.
- A cross-site request forgery (CSRF) was discovered in the accessibility mode of widget editing. Reported by Ronnie Skansing.
- Weak cryptographic security for multisite activation key. Reported by Jack.
