CVE-2026-30854

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

Description

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. From version 9.3.1-alpha.3 to before version 9.5.0-alpha.10, 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. This issue has been patched in version 9.5.0-alpha.10.
