Description
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.
