CVE-2025-53364Network attack vector

Schema metadata disclosure via unauthenticated GraphQL introspection

Published Jul 10, 2025 · Updated Jul 10, 2025

Information disclosure in Parse Server 5.3.0 through 7.5.2 and 8.0.0 through 8.2.1 allows remote attackers to read schema metadata. The Apollo GraphQL request path processed introspection operations without checking for a session token or master key, returning the schema to public callers. A network-reachable mounted GraphQL endpoint is sufficient; the response exposes metadata rather than stored application data.
