WordPress 4.7.3

WordPress versions 4.7.2 and earlier are affected by six security issues. We advise all WordPress users to update their websites to the latest version to prevent the abuse of these issues.

Security Issues

  • 3 Cross-site Scripting exploits through various means.
  • A Cross-site request forgery exploit that leads to excessive resource usage.
  • Unintended file deletion which can be accessed via the plugin deletion functionality.
  • URL validation redirects which can be utilised through the use of control characters.

We advise all WordPress users to update to 4.7.3 immediately to prevent the risk of a site compromise.

Updating WordPress is as simple as navigating to DashboardUpdates and clicking Update Now or alternatively by downloading directly.
Your website may be up to date if your site supports automatic background updates, so in cases there may be no need to manually update.

As always, our thanks goes to the great community members acting out responsible disclosure, and the amazing WordPress development team for their quick patching.
Don’t delay, upgrade today!
