+  "details": "### Summary\n\nAn authenticated low-privileged user can call `assets/preview-file` for an asset they are not authorized to view and still receive preview response data (`previewHtml`) for that private asset.\n\nThe returned preview HTML included a private preview image route containing the target private `assetId`, even though `canView` was `false` for the attacker account.\n\n### Details\n\n1. `assets/preview-file` accepts a maliciously controlled `assetId` and renders preview output.\n2. The action does not enforce per-asset view authorization prior to returning preview content.\n 3. As a result, an authenticated user without asset-view permission can still obtain private preview output.\n\nThis affects Craft installations with authenticated users of mixed privilege levels with private assets.\n\n### Resources\n\n- d30df3112220db1ffd6726a3ed11857014c7fb27\n- b1cddf72c98a",
