{"id":"CVE-2026-30947","summary":"Parse Server ha a bypass of class-level permissions in LiveQuery","details":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. 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.","aliases":["BIT-parse-2026-30947","GHSA-7ch5-98q2-7289"],"modified":"2026-04-10T05:42:02.248396Z","published":"2026-03-10T20:16:34.731Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30947.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-863"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/parse-community/parse-server","events":[{"introduced":"0"},{"fixed":"20abb1cf36214d05b4be7a081a41c6df5becf42b"}]}],"versions":["2.0.0","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","2.0.6","2.0.7","2.0.8","2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.1.5","2.1.6","2.2.0","2.2.1","2.2.10","2.2.11","2.2.12","2.2.13","2.2.14","2.2.15","2.2.16","2.2.17","2.2.18","2.2.19","2.2.2","2.2.20","2.2.21","2.2.22","2.2.23","2.2.24","2.2.25","2.2.25-beta.1","2.2.3","2.2.4","2.2.5","2.2.6","2.2.7","2.2.8","2.2.9","2.3.1","2.3.2","2.3.3","2.3.4","2.3.5","2.3.6","2.3.7","2.3.8","2.4.0","2.4.1","2.4.2","2.5.0","2.5.1","2.5.2","2.5.3","2.6.0","2.6.1","2.6.2","2.6.3","2.6.4","2.6.5","2.7.0","2.7.1","2.7.2","2.7.3","2.7.4","2.8.0","2.8.2","3.0.0","3.1.0","3.1.1","3.1.2","3.1.3","3.10.0","3.2.0","3.2.1","3.2.2","3.2.3","3.3.0","3.4.0","3.4.1","3.5.0","3.6.0","3.7.0","3.7.1","3.7.2","3.8.0","3.9.0","4.0.0","4.0.1","4.0.2","4.1.0","4.2.0","4.3.0","4.4.0","4.5.0","5.0.0","5.0.0-alpha.1","5.1.0","5.1.1","5.2.0","5.2.1","5.2.2","5.2.3","5.2.4","5.2.5","5.2.6","5.2.7","5.2.8","5.3.0","5.3.1","5.3.2","5.3.3","5.4.0","6.0.0","6.1.0","6.2.0","6.2.1","6.2.2","6.3.0","6.3.1","6.4.0","7.0.0","7.1.0","7.2.0","7.3.0","7.4.0","8.0.0","8.0.1","8.0.2","8.1.0","8.2.0","8.2.1","8.2.2","8.2.3","8.2.4","8.2.5","8.3.0","8.4.0","8.5.0","8.6.0","8.6.1","8.6.10","8.6.11","8.6.12","8.6.13","8.6.14","8.6.15","8.6.2","8.6.3","8.6.4","8.6.5","8.6.6","8.6.7","8.6.8","8.6.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-30947.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
