Description

Parse Server: Classes _GraphQLConfig and _Audience master key bypass via generic class routes

Impact

The _GraphQLConfig and _Audience internal classes can be read, modified, and deleted via the generic /classes/_GraphQLConfig and /classes/_Audience REST API routes without master key authentication. This bypasses the master key enforcement that exists on the dedicated /graphql-config and /push_audiences endpoints. An attacker can read, modify and delete GraphQL configuration and push audience data.

Patches

The fix adds the affected internal classes to the classesWithMasterOnlyAccess list, ensuring that the generic /classes/ routes enforce master key access consistently with the dedicated endpoints.

Workarounds

There is no known workaround.
