CWE-79  (opens in a new tab)

How to fix?

Upgrade Debian:12 wordpress to version 5.3.2+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.

In WordPress before 5.3.1, authenticated users with lower privileges (like contributors) can inject JavaScript code in the block editor, which is executed within the dashboard. It can lead to an admin opening the affected post in the editor leading to XSS.
