WordPress 4.9.5 is now available. This is a security and maintenance release for all versions since WordPress 3.7. We strongly encourage you to update your sites immediately. Please login into your Dashboard ? Updates and click “Update Now”. Sites that support automatic background updates are already beginning to update automatically.
WordPress versions 4.9.4 and earlier are affected by three security issues. As part of the core team’s ongoing commitment to security hardening, the following fixes have been implemented in 4.9.5:
- Don’t treat
localhostas same host by default.
- Use safe redirects when redirecting the login page if SSL is forced.
- Make sure the version string is correctly escaped for use in generator tags.
