    DRUPAL-CORE-2026-016

    Published: 14 Oct 2026Last Modified: 17 Oct 2026

    Summary:

    Details: The Navigation module doesn't sufficiently sanitize certain attributes, which can lead to a cross-site scripting (XSS) vulnerability. This vulnerability is mitigated by the fact that an attacker must have a role with permission to enter HTML tags containing specific data attributes, or the `administer menu` permission.
