Description

**WordPress 5.4.2 Security and Maintenance Release**

This security and maintenance release features 23 fixes and enhancements. Plus, it adds a number of security fixes—see the list below.

These bugs affect WordPress versions 5.4.1 and earlier; version 5.4.2 fixes them, so you’ll want to upgrade.

**Security Updates**

 - Props to Sam Thomas (jazzy2fives) for finding an XSS issue where authenticated users with low privileges are able to add JavaScript to posts in the block editor.

 - Props to Luigi – (gubello.me) for discovering an XSS issue where authenticated users with upload permissions are able to add JavaScript to media files.

 - Props to Ben Bidner of the WordPress Security Team for finding an open redirect issue in wp_validate_redirect().

 - Props to Nrimo Ing Pandum for finding an authenticated XSS issue via theme uploads.

 - Props to Simon Scannell of RIPS Technologies for finding an issue where set-screen-option can be misused by plugins leading to privilege escalation.

 - Props to Carolina Nymark for discovering an issue where comments from password-protected posts and pages could be displayed under certain conditions.
