An unauthenticated caller who knows only the public application id can iteratively send malformed queries to reconstruct class names, field names, argument names, mutation names, and input-object fields. This bypasses the `IntrospectionControlPlugin` enforced when `graphQLPublicIntrospection: false` (the default) and defeats the schema-hiding goal of prior advisories GHSA-48q3-prgv-gm4w and GHSA-q5q9-2rhp-33qw. Schema disclosure aids reconnaissance for downstream authorization probing but does not by itself leak object data or authentication material.\n\n### Patches\n\nA new `SchemaSuggestionsControlPlugin` Apollo plugin strips the `Did you mean ...?` suffix from GraphQL validation-error messages during `validationDidStart`, which runs before any introspection gate. The plugin applies only when `graphQLPublicIntrospection: false` and the caller is not a master-key or maintenance-key holder, matching the trust model of the existing `IntrospectionControlPlugin`.\n\n### Workarounds\n\nNo code workaround is available short of disabling the GraphQL API (`mountGraphQL: false`). Operators who require disclosure-resistant validation errors should upgrade to a patched release.\n\n### Resources\n\n- GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-8cph-rgr4-g5vj\n- Fix Parse Server 9: https://github.com/parse-community/parse-server/pull/10467\n- Fix Parse Server 8: https://github.com/parse-community/parse-server/pull/10468","state":0,"publishedAt":"2026-05-29T19:18:01+00:00","modifiedAt":"2026-06-16T13:26:19.3055104+00:00","affected":[{"ecosystem":"npm","name":"parse-server","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"9.0.0"},{"kind":"fixed","version":"9.9.1-alpha.2"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"parse-server","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"8.6.78"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/parse-community/parse-server/security/advisories/GHSA-8cph-rgr4-g5vj","https://nvd.nist.gov/vuln/detail/CVE-2026-47248","https://github.com/parse-community/parse-server/pull/10467","https://github.com/parse-community/parse-server/pull/10468","https://github.com/parse-community/parse-server"],"sourceUrl":"https://github.com/advisories/GHSA-8cph-rgr4-g5vj","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-8cph-rgr4-g5vj","identifiers":["GHSA-8cph-rgr4-g5vj","BIT-parse-2026-47248","CVE-2026-47248"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
