WordPress 5.4.1 has been released.

WordPress 5.4.1 is a short-cycle security and maintenance release.

As noted on the official WordPress blog.

This security and maintenance release features 17 bug fixes in addition to 7 security fixes. Because this is a security release, it is recommended that you update your website immediately.

The version 5.4.1 is a short-cycle security and maintenance release. The next major release will be version 5.5.

Security Updates

Seven security issues affect WordPress versions 5.4 and earlier. If you have not yet updated to 5.4, all WordPress versions since 3.7 have also been updated to fix the following security issues:

  • Props to Muaz Bin Abdus Sattar and Jannes who both independently reported an issue where password reset tokens were not properly invalidated
  • Props to ka1n4t for finding an issue where certain private posts can be viewed unauthenticated
  • Props to Evan Ricafort for discovering an XSS issue in the Customizer
  • Props to Ben Bidner from the WordPress Security Team who discovered an XSS issue in the search block
  • Props to Nick Daugherty from WordPress VIP / WordPress Security Team who discovered an XSS issue in wp-object-cache
  • Props to Ronnie Goodrich (Kahoots) and Jason Medeiros who independently reported an XSS issue in file uploads.
  • Props to Weston Ruter for fixing a stored XSS vulnerability in the WordPress customizer.
  • Additionally, an authenticated XSS issue in the block editor was discovered by Nguyen the Duc in WordPress 5.4 RC1 and RC2. It was fixed in 5.4 RC5. We wanted to be sure to give credit and thank them for all of their work in making WordPress more secure.

All WordPress websites managed by Akuto Enterprise Ltd who own the Maintenance & Security Package will be updated schematically, therefore, no action is required.
