Prior to versions 8.6.78 and 9.9.1-alpha.2, Parse Server's GraphQL endpoint discloses schema metadata to unauthenticated callers through Did you mean ...? suggestions embedded in GraphQL validation-error messages. 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 issue has been patched in versions 8.6.78 and 9.9.1-alpha.2.","published":"2026-06-12T18:21:31.511Z","modified":"2026-08-12T03:51:34.163672859Z","cvss":null,"epss":{"score":0.00291,"percentile":0.21175,"asOf":"2026-08-26"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"parse-server","fixedVersion":"9.9.1-alpha.2"},{"ecosystem":"npm","name":"parse-server","fixedVersion":"8.6.78"}],"fix":{"url":"https://github.com/parse-community/parse-server/pull/10467","label":"parse-community/parse-server#10467"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47248.json"},{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-8cph-rgr4-g5vj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47248"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/pull/10467"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/pull/10468"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:34.163672859Z"}}
