CyberRota Analysis
AI-GeneratedAffected versions of Parse Server expose the names of required custom input fields through GraphQL validation error messages, even when public introspection is disabled. This vulnerability allows unauthenticated clients with only the public application ID to infer the structure of the database schema, potentially leading to information disclosure. Organizations using vulnerable versions should prioritize remediation to protect against unintended schema exposure.

Original NVD Description
Parse Server versions >= 9.0.0 before 9.10.0-alpha.5 and >= 8.2.2 before 8.6.86 return GraphQL validation error messages that name required custom input fields even when public introspection is disabled (graphQLPublicIntrospection: false, the default). A client holding only the public application id — with no user session, master key, or maintenance key — can trigger validation errors to learn the names of required (non-null) custom fields on classes it already references by name, partially defeating the schema-hiding intent of disabling public introspection. No stored data, credentials, optional field names, unreferenced class names, or Cloud Code function names are exposed.
