A Cross Site Scripting (XSS) vulnerability was identified in Amadou theme's
themes_links() function in the template.php file, which was fixed in the

Drupal core is not affected. If you do not use the contributed Amadou [4]
theme, there is nothing you need to do.

If you have created a custom theme with Amadou or are using Amadou as a base
theme, please see below for a manual fix:
