Mô tả

Impact

Class-level permissions (CLP) are not enforced for LiveQuery subscriptions. An unauthenticated or unauthorized client can subscribe to any LiveQuery-enabled class and receive real-time events for all objects, regardless of CLP restrictions.

All Parse Server deployments that use LiveQuery with class-level permissions are affected. Data intended to be restricted by CLP is leaked to unauthorized subscribers in real time.

Patches

The fix enforces CLP before creating the subscription and during event delivery.

Workarounds

Disable LiveQuery for classes that use CLP restrictions by removing them from the liveQuery.classNames server configuration.
