Information disclosure in Parse Server GraphQL endpoint allows unauthenticated clients to learn names of required custom fields by triggering validation errors, partially bypassing schema hiding when public introspection is disabled. Affects versions 8.2.2 to 8.6.85 and 9.0.0 to 9.9.x; patched in 8.6.86 and 9.10.0-alpha.5. No active exploitation or public exploit code identified.

Lifecycle Timeline
1DescriptionCVE.org
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.
