How to fix?

Upgrade Debian:unstable wordpress to version 5.5.3+dfsg1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream wordpress package and not the wordpress package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

is_blog_installed in wp-includes/functions.php in WordPress before 5.5.2 improperly determines whether WordPress is already installed, which might allow an attacker to perform a new installation, leading to remote code execution (as well as a denial of service for the old installation).
