From the [WordPress 4.9.7 release post](https://make.wordpress.org/core/2018/07/05/wordpress-4-9-7/),
WordPress versions 4.9.6 and earlier are affected by one security issue. As part
of the core team’s ongoing commitment to security hardening, the following security
and maintenance fixes have been implemented:

 1. WordPress versions 4.9.6 and earlier are affected by a file deletion issue where
    a user with the capability to edit and delete media files could potentially manipulate
    media metadata to attempt to delete files outside the uploads directory.
 2. Taxonomy: Improve cache handling for term queries.
 3. Posts, Post Types: Clear post password cookie when logging out.
 4. Widgets: Allow basic HTML tags in sidebar descriptions on Widgets admin screen.
 5. Community Events Dashboard: Always show the nearest WordCamp if one is coming up,
    even if there are multiple Meetups happening first.
 6. Privacy: Make sure default privacy policy content does not cause a fatal error 
    when flushing rewrite rules outside of the admin context.
