WordPress 4.3.1 Security and Maintenance Release

Posted September 15, 2015 by Samuel Sidler. Filed under Releases, Security.

WordPress 4.3.1 is now available. This is a security release for all previous versions and we strongly encourage you to update your sites immediately.

This release addresses three issues, including two cross-site scripting vulnerabilities and a potential privilege escalation.

  • WordPress versions 4.3 and earlier are vulnerable to a cross-site scripting vulnerability when processing shortcode tags (CVE-2015-5714). Reported by Shahar Tal and Netanel Rubin of Check Point.
  • A separate cross-site scripting vulnerability was found in the user list table. Reported by Ben Bidner of the WordPress security team.
  • Finally, in certain cases, users without proper permissions could publish private posts and make them sticky (CVE-2015-5715). Reported by Shahar Tal and Netanel Rubin of Check Point.

Our thanks to those who have practiced responsible disclosure of security issues.

WordPress 4.3.1 also fixes twenty-six bugs. For more information, see the release notes or consult the list of changes.
