Summary

Parse Server: GraphQL `__type` introspection bypass via inline fragments when public introspection is disabled

Details

Impact

When graphQLPublicIntrospection is disabled, __type queries nested inside inline fragments (e.g. ... on Query { __type(name:"User") { name } }) bypass the introspection control, allowing unauthenticated users to perform type reconnaissance. __schema introspection is not affected.

Patches

The check was changed from a flat iteration over root-level selections to a recursive walk of all selection sets, detecting __type inside inline fragments at any depth.

Workarounds

Require master key authentication at the network layer (e.g. reverse proxy) for the GraphQL endpoint.
