GHSA-7xg7-rqf6-pw6c
Summary Parse Server: Classes `_GraphQLConfig` and `_Audience` master key bypass via generic class routes 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.
