{"id":"BIT-parse-2026-64627","summary":"Parse Server 9.0.0 Schema Disclosure via GraphQL Variable Coercion","details":"Parse Server versions \u003e= 9.0.0 before 9.10.0 and versions before 8.6.85 contain a schema disclosure vulnerability. 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 and 8.6.85.","aliases":["CVE-2026-64627","GHSA-9g8f-h8f3-hjcm"],"modified":"2026-09-25T15:55:29.938501075Z","published":"2026-09-25T15:21:58.248Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*"]},"references":[{"type":"WEB","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-9g8f-h8f3-hjcm"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64627"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/parse-server-schema-disclosure-via-graphql-variable-coercion"}],"affected":[{"package":{"name":"parse","ecosystem":"Bitnami","purl":"pkg:bitnami/parse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.6.85"},{"introduced":"9.0.0"},{"fixed":"9.10.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/parse/BIT-parse-2026-64627.json"},"severity":[{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
