Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2-alpha.12 and 8.6.25, 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. This vulnerability is fixed in 9.5.2-alpha.12 and 8.6.25.
