CWE-79  (opens in a new tab)

How to fix?

Upgrade Debian:12 wordpress to version 4.9.1+dfsg-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.

wp-includes/general-template.php in WordPress before 4.9.1 does not properly restrict the lang attribute of an HTML element, which might allow attackers to conduct XSS attacks via the language setting of a site.
