CWE-79  (opens in a new tab)

How to fix?

Upgrade Debian:12 wordpress to version 5.8.1+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:12 relevant fixed versions and status.

WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. ### Impact The issue allows an authenticated but low-privileged user (like contributor/author) to execute XSS in the editor. This bypasses the restrictions imposed on users who do not have the permission to post unfiltered_html. #
