WordPress 4.7.1 updates for 8 security breaches

WordPress 4.7.1 was officially released on January 11, providing users of the popular open-source content management system with an incremental update fixing 62 bugs and 8 security issues. WordPress developers are encouraging users of the content management system to apply a new update, pushed this week, to resolve these security issues, including a handful of cross-site scripting (XSS) and cross-site request forgery (CSRF) bugs. In this article,  more details on these 8 security issues and a good way to fix WordPress security breaches for good.

While Vaughan (nick-name in honor of legendary American jazz vocalist Sarah “Sassy” Vaughan), has been enthusiastically received since its release in December, developers say versions 4.7 and earlier are affected by at least eight security issues and a number of bugs. To fix these issues, WordPress developers this week announced the immediate availability of WordPress 4.7.1 security and maintenance updates. WordPress 4.7.1 also fixes 62 bugs from 4.7.

WordPress versions 4.7 and earlier are affected by eight security issues:

  1. 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 fixed in PHPMailer thanks to Dawid Golunski and Paul Buonopane.
  2. 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.
  3. Cross-site scripting (XSS) via the plugin name or version header on update-core.php. Reported by Dominik Schilling of the WordPress Security Team.
  4. Cross-site request forgery (CSRF) bypass via uploading a Flash file. Reported by Abdullah Hussam.
  5. Cross-site scripting (XSS) via theme name fallback. Reported by Mehmet Ince.
  6. Post via email checks if default settings aren’t changed. Reported by John Blackbourn of the WordPress Security Team.
  7. A cross-site request forgery (CSRF) was discovered in the accessibility mode of widget editing. Reported by Ronnie Skansing.
  8. Weak cryptographic security for a multisite activation key. Reported by Jack.

Websites that support automatic background updates are reportedly already beginning to update to WordPress 4.7.1. If your business website has not automatically updated, you can download WordPress 4.7.1 or head over to Dashboard -> Updates and simply click “Update Now.”
