Craft CMS: Anonymous "assets/image-editor" calls returns private asset editor metadata to unauthorized users
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, 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. This issue has been patched in versions 4.17.8 and 5.9.14.
