CVE-2019-16780

Priority
Description
WordPress users with lower privileges (like contributors) can inject
JavaScript code in the block editor using a specific payload, which is
executed within the dashboard. This can lead to XSS if an admin opens the
post in the editor. Execution of this attack does require an authenticated
user. This has been patched in WordPress 5.3.1, along with all the previous
WordPress versions from 3.7 to 5.3 via a minor release. Automatic updates
are enabled by default for minor releases and we strongly recommend that
you keep them enabled.
