CVE-2026-31800

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

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.
