## Affected

- netbox-community netbox: through 4.7.0

## Description

NetBox through 4.7.0 fails to properly scope user-private records in REST and GraphQL API endpoints for Notifications, Subscriptions, and Bookmarks. Authenticated users with view permissions can access all users' private records through unscoped querysets, disclosing which users watch or bookmark which objects.

## What to do
