Details

As written in the advisory (Markdown source, shown as plain text).

### 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. ### References - GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-7ch5-98q2-7289 - Fix Parse Server 9: https://github.com/parse-community/parse-server/releases/tag/9.5.2-alpha.3 - Fix Parse Server 8: https://github.com/parse-community/parse-server/releases/tag/8.6.16
