CVE-2026-33161: Craft CMS: Anonymous "assets/image-editor" calls returns private asset editor metadata to unauthorized users
Summary
A low-privileged authenticated user can call assets/image-editor with the ID of a private asset they cannot view and still receive editor response data, including focalPoint.
The endpoint returns private editing metadata without per-asset authorization validation.
Root-cause analysis:
1. actionImageEditor() accepts assetId from the request body. 2. The asset is loaded, and the focal-point data is read. 3. Response returns html and focalPoint. 4. No explicit authorization check is applied before the response.
Impact
Affected deployments:
Craft sites where asset edit metadata should remain restricted to authorized users.
Security consequence:
Unauthorized users can extract private editor metadata and related editor context for inaccessible assets.
