SCA: security update for craftcms/cms (GHSA-x76w-8c62-48mg)

medium Tenable Cloud Security Plugin ID 445785

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Craft CMS contains a missing authorization vulnerability in the assets/preview-thumb endpoint. A Control
 Panel user without permission to view a target private asset can call the endpoint with an attacker-
 controlled assetId and receive preview HTML containing a signed fallback transform preview link for that
 private asset, because no asset-view permission check is performed before preview generation. This affects
 versions >= 4.0.0-RC1, <= 4.17.7 and >= 5.0.0-RC1, <= 5.9.13, and is fixed in 4.17.8 and 5.9.14.

Update the craftcms/cms library and its related packages to version 4.17.8 or later.
