## Affected

- uselotus lotus: through 0.10.2

## Description

Lotus through 0.10.2 contains an insecure direct object reference vulnerability in SubscriptionViewSet.get_object() that uses an unscoped queryset without organization filtering or permission checks. Authenticated users or API keys from any organization can supply another organization's subscription_id to read, cancel, update, switch plans, or modify addons, altering another tenant's billing.
