Upgrade craftcms/cms to version 5.9.18 or higher.
Overview
craftcms/cms is a content management system.
Affected versions of this package are vulnerable to Missing Authorization via the actionShowInFolder process. An attacker can access sensitive asset filenames and complete folder structures, including volume handles and URIs, by supplying arbitrary asset IDs without the necessary volume permissions. This is only exploitable if the attacker is an authenticated control panel user with only accessCp permission.
