Prior to 9.5.2-alpha.3 and 8.6.16, class-level permissions (CLP) are not enforced for LiveQuery subscriptions. An unauthenticated or unauthorized client can subscribe to any LiveQuery-enabled class and receive real-time events for all objects, regardless of CLP restrictions. All Parse Server deployments that use LiveQuery with class-level permissions are affected. Data intended to be restricted by CLP is leaked to unauthorized subscribers in real time. This vulnerability is fixed in 9.5.2-alpha.3 and 8.6.16.","published":"2026-03-10T20:16:34.731Z","modified":"2026-08-07T11:50:52.162368312Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"parse-server","fixedVersion":"9.5.2-alpha.3"},{"ecosystem":"npm","name":"parse-server","fixedVersion":"8.6.16"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/parse-community/parse-server/releases/tag/8.6.16"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/releases/tag/9.5.2-alpha.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30947.json"},{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-7ch5-98q2-7289"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-30947"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:52.162368312Z"}}
