CVE-2026-64627Network attack vector

Schema disclosure via GraphQL variable-coercion suggestions

Published Jul 21, 2026 · Updated Jul 21, 2026

Information disclosure in Parse Server before 8.6.85 and 9.0.0 through 9.10.0-alpha.3 allows remote attackers to recover schema names. With public introspection disabled, the variable-coercion path returns schema-derived correction suggestions because validation-only filtering does not cover those errors. Possession of the public application id is sufficient to enumerate Cloud Code function, class, and field names; no data modification or service interruption is reported.
