Plane is an an open-source project management tool. Prior to version 1.2.2, the "ProjectAssetEndpoint.patch()" method in "apps/api/plane/app/views/asset/v2.py" (lines 579–593) performs a global asset lookup using only the asset ID ("pk") via "FileAsset.objects.get(id=pk)", without verifying that the asset belongs to the workspace and project specified in the URL path. This allows any authenticated user (including those with the GUEST role) to modify the "attributes" and "is_uploaded" status of assets belonging to any workspace or project in the entire Plane instance by guessing or enumerating asset UUIDs. Version 1.2.2 fixes the issue.
