How to fix?

Upgrade parse-server to version 8.6.78, 9.9.1-alpha.2 or higher.

Overview

parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js.

Affected versions of this package are vulnerable to Information Exposure via the Did you mean ...? suggestions in GraphQL validation-error messages. An attacker can enumerate schema metadata, such as class names, field names, argument names, mutation names, and input-object fields, by sending malformed queries to the GraphQL endpoint.

Note:

  1. This is only exploitable if the GraphQL API is enabled and the attacker is unauthenticated while graphQLPublicIntrospection is set to false.

  2. This vulnerability bypasses the IntrospectionControlPlugin enforced when graphQLPublicIntrospection: false (the default) and defeats the schema-hiding goal of prior advisories CVE-2026-30854 and CVE-2025-53364.
