CVE-2026-33160 Details
Description
Craft CMS is a content management system (CMS). From version 4.0.0-RC1 to before version 4.17.8 and from version 5.0.0-RC1 to before version 5.9.14, an unauthenticated user can call assets/generate-transform with a private assetId, receive a valid transform URL, and fetch transformed image bytes. The endpoint is anonymous and does not enforce per-asset authorization before returning the transform URL. This issue has been patched in versions 4.17.8 and 5.9.14.
An access control vulnerability has been identified in Craft CMS versions 4.0.0-RC1 prior to 4.17.8 and 5.0.0-RC1 prior to 5.9.14. The issue allows unauthenticated users to access private assets by calling the 'assets/generate-transform' endpoint with a private asset ID. The endpoint, which is anonymous, does not verify authorization for individual assets before providing a transform URL. This oversight enables guest users to retrieve content from private assets if the transform output is accessible.
Users can upgrade to Craft CMS versions 4.17.8 or 5.9.14 to address this vulnerability.
