Description
Summary
A low-privileged authenticated user can read private asset content by calling assets/edit-image with an arbitrary assetId that they are not authorized to view.
The endpoint returns image bytes (or a preview redirect) without enforcing a per-asset view authorization check, leading to potential unauthorized disclosure of private files.
Details
Root cause:
- A user-controlled object reference (
assetId) is used to load and return sensitive content.
- The action does not verify whether the current user is authorized to view that asset.
- This creates an authenticated IDOR / authorization bypass.
Impact
- Craft installations where private/non-public assets exist and low-privileged users can authenticate.
