When the GraphQL API is mounted with public introspection disabled (graphQLPublicIntrospection: false, the default), schema-derived 'Did you mean ...?' suggestions were still returned in GraphQL error messages produced during variable coercion, which were not covered by the introspection-hardening control (that only handled validation errors). An unauthenticated caller possessing only the public application id can iteratively recover hidden schema identifiers — including registered Cloud Code function names and Parse class and field names — by submitting queries or mutations whose variables contain near-miss enum values or input-object field names. This is a follow-up bypass of GHSA-8cph-rgr4-g5vj. The issue is fixed in 9.10.0-alpha.4 and 8.6.85."}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Generation of Error Message Containing Sensitive Information","cweId":"CWE-209","type":"CWE"}]}],"affected":[{"vendor":"parse-community","product":"parse-server","defaultStatus":"unaffected","packageURL":"pkg:npm/parse-server","versions":[{"version":"9.0.0","status":"affected","versionType":"semver","lessThan":"9.10.0-alpha.4"},{"version":"9.10.0-alpha.4","status":"unaffected","versionType":"semver"}]},{"vendor":"parse-community","product":"parse-server","defaultStatus":"unaffected","packageURL":"pkg:npm/parse-server","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"8.6.85"},{"version":"8.6.85","status":"unaffected","versionType":"semver"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*","versionStartIncluding":"9.0.0","versionEndExcluding":"9.10.0-alpha.4"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*","versionEndExcluding":"8.6.85"}]}]}],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","vectorString":"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","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"LOW","vulnIntegrityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","baseScore":6.9,"baseSeverity":"MEDIUM"}}],"references":[{"url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-9g8f-h8f3-hjcm","name":"GitHub Security Advisory (GHSA-9g8f-h8f3-hjcm)","tags":["vendor-advisory"]},{"name":"VulnCheck Advisory: Parse Server 9.0.0 Schema Disclosure via GraphQL Variable Coercion","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/parse-server-schema-disclosure-via-graphql-variable-coercion"}],"credits":[{"lang":"en","value":"offset","type":"reporter"},{"lang":"en","value":"mtrezza","type":"coordinator"}],"x_generator":{"engine":"vulncheck-endgame"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-21T13:11:04.531501Z","id":"CVE-2026-64627","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-21T14:55:23.663Z"}}]}}
