Craft CMS' anonymous "assets/image-editor" calls return private asset editor metadata to unauthorized users

CVE-2026-33161 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

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.
