Affected packages

• npm parse-server: >= 9.0.0-alpha.1, < 9.5.2-alpha.12 → fixed in 9.5.2-alpha.12 • npm parse-server: < 8.6.25 → fixed in 8.6.25

Description

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.
