  "details": "We have identified an authorization issue in Craft CMS where a forced folder move can delete a conflicting destination folder without destination delete permission.\n\n### Description\n\nCraft CMS\u2019s `craft\\\\controllers\\\\AssetsController::actionMoveFolder()` supports moving an asset folder into a destination parent folder. If a folder with the same name already exists at the destination, the action can be called with `force=true` to overwrite the destination.\n\nThe permission checks for this action allow:\n\n- `deleteAssets:\u003csourceVolumeUid\u003e` for the folder being moved  \n- `createFolders:\u003cdestVolumeUid\u003e` for the destination parent folder  \n- `saveAssets:\u003cdestVolumeUid\u003e` for the destination parent folder\n\nThe action does not require `deleteAssets` on the destination volume or destination conflict folder. When `force=true` and a name conflict exists, the code deletes the destination folder to resolve the conflict.\n\n```php\n$this-\u003erequireVolumePermissionByFolder(\u0027deleteAssets\u0027, $folderToMove);\n$this-\u003erequireVolumePermissionByFolder(\u0027createFolders\u0027, $destinationFolder);\n$this-\u003erequireVolumePermissionByFolder(\u0027saveAssets\u0027, $destinationFolder);\n```\n\n[*src/controllers/AssetsController.php:L751-L753*](https://github.com/craftcms/cms/blob/5.x/src/controllers/AssetsController.php#L751-L753)\n\nIndexed destination conflicts are deleted via the Assets service:\n\n```php\n$assets-\u003edeleteFoldersByIds($existingFolder-\u003eid);\n```\n\n[*src/controllers/AssetsController.php:L798-L798*](https://github.com/craftcms/cms/blob/5.x/src/controllers/AssetsController.php#L798-L798)\n\nUnindexed destination conflicts are deleted directly in the volume filesystem:\n\n```php\n$targetVolume-\u003edeleteDirectory(rtrim($destinationFolder-\u003epath, \u0027/\u0027) . \u0027/\u0027 . $folderToMove-\u003ename);\n```\n\n[*src/controllers/AssetsController.php:L815*](https://github.com/craftcms/cms/blob/5.x/src/controllers/AssetsController.php#L815)\n\n### Impact\n\nA user who cannot delete assets in a destination volume can still delete a destination folder and its contents by triggering a forced move into a conflicting name. This can cause asset loss, broken references in entries and fields that point to deleted assets, and operational disruption.",
