Impact
Authenticated users with upload permissions (like authors) are able to inject JavaScript into some media file attachment pages in a certain way. This can lead to script execution in the context of a higher privileged user when the file is viewed by them.
Patches
This has been patched in WordPress 5.4.2, along with all the previously affected versions via a minor release. Automatic updates are enabled by default for minor releases and we strongly recommend that you keep them enabled.
