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 &gt;= 4.0.0-RC1, &lt;= 4.17.7 and &gt;= 5.0.0-RC1, &lt;= 5.9.13, and is fixed in 4.17.8 and 5.9.14.</p> <p>Craft CMS contains a missing authorization vulnerability in the assets/preview-thumb endpoint.
