{"id":"CVE-2026-100632","state":"PUBLISHED","title":"Parse Server 9.0.0 before 9.10.1 Protected Fields Disclosure via LiveQuery","description":"Parse Server is an open-source backend server. In versions >= 9.0.0 and < 9.10.1-alpha.8, and in versions < 8.6.89, LiveQuery evaluates the protectedFields class-level permission against an incompletely resolved caller identity: the subscriber's roles are not resolved, and when a subscription does not supply its own session token the event payload is redacted against an anonymous identity even though the read was authorized against the connected user. As a result, field masks defined for a role, for authenticated users, or for a specific user are not applied, so an authenticated subscriber can receive field values that the REST API correctly withholds and can use a masked field to filter or watch a subscription. Only classes with LiveQuery enabled that define protectedFields under a role:, authenticated, or per-user group are affected; masks under the public (*) group are applied correctly. The issue is fixed in 9.10.1-alpha.8 and 8.6.89. As a workaround, additionally define the affected field masks under the public (*) group, or disable LiveQuery for classes whose class-level permissions rely on role-scoped, authenticated, or per-user protectedFields groups.","publishedAt":"2026-09-26T13:23:07.825Z","updatedAt":"2026-09-28T16:49:03.774Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["parse-community parse-server"],"affected":[{"vendor":"parse-community","product":"parse-server","packageURL":"pkg:npm/parse-server","defaultStatus":"unaffected","versions":[{"version":"9.0.0","status":"affected","lessThan":"9.10.1-alpha.8","versionType":"semver"},{"version":"9.10.1-alpha.8","status":"unaffected","versionType":"semver"}]},{"vendor":"parse-community","product":"parse-server","packageURL":"pkg:npm/parse-server","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"8.6.89","versionType":"semver"},{"version":"8.6.89","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/parse-community/parse-server/security/advisories/GHSA-9jpp-xhh6-75mf","https://www.vulncheck.com/advisories/parse-server-9.0.0-before-9.10.1-protected-fields-disclosure-via-livequery"],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/100xxx/CVE-2026-100632.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-100632","state":"PUBLISHED","datePublished":"2026-09-26T13:23:07.825Z","dateUpdated":"2026-09-28T16:49:03.774Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-26T02:31:42.100Z"},"containers":{"cna":{"title":"Parse Server 9.0.0 before 9.10.1 Protected Fields Disclosure via LiveQuery","descriptions":[{"lang":"en","value":"Parse Server is an open-source backend server.
