CVE-2026-66008

Parse Server versions >= 9.0.0 before 9.10.0-alpha.6 and >= 8.2.2 before 8.6.87 disclose Pointer and Relation target class names through GraphQL validation and input-coercion error messages when public schema introspection is disabled (graphQLPublicIntrospection: false, the default). Because these errors are produced before authentication, authorization, or any resolver runs, an unauthenticated client possessing only the public application ID can trigger errors on Pointer or Relation fields to reconstruct hidden schema class names, partially defeating the schema-hiding protection. Only schema metadata (class names) is exposed; no object data, credentials, or user records are disclosed.

Summary		(es) Las versiones de Parse Server >= 9.0.0 anteriores a 9.10.0-alpha.6 y >= 8.2.2 anteriores a 8.6.87 revelan nombres de clases objetivo de Pointer y Relation a través de mensajes de error de validación de GraphQL y de coerción de entrada cuando la introspección pública del esquema está deshabilitada (graphQLPublicIntrospection: false, el valor predeterminado). Debido a que estos errores se producen antes de la autenticación, la autorización o la ejecución de cualquier resolvedor, un cliente no autenticado que posee solo el ID de aplicación público puede activar errores en campos Pointer o Relation para reconstruir nombres de clases de esquema ocultos, derrotando parcialmente la protección de ocultación del esquema. Solo se exponen metadatos del esquema (nombres de clases); no se divulgan datos de objetos, credenciales o registros de usuario.
