{"id":"GHSA-7ch5-98q2-7289","summary":"Parse Server has a bypass of class-level permissions in LiveQuery","details":"### Impact\n\nClass-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.\n\nAll 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.\n\n### Patches\n\nThe fix enforces CLP before creating the subscription and during event delivery.\n\n### Workarounds\n\nDisable LiveQuery for classes that use CLP restrictions by removing them from the `liveQuery.classNames` server configuration.\n\n### References\n\n- GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-7ch5-98q2-7289\n- Fix Parse Server 9: https://github.com/parse-community/parse-server/releases/tag/9.5.2-alpha.3\n- Fix Parse Server 8: https://github.com/parse-community/parse-server/releases/tag/8.6.16","aliases":["BIT-parse-2026-30947","CVE-2026-30947"],"modified":"2026-03-14T03:40:56.870635Z","published":"2026-03-11T00:17:16Z","database_specific":{"cwe_ids":["CWE-863"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-03-11T00:17:16Z","nvd_published_at":"2026-03-10T21:16:47Z"},"references":[{"type":"WEB","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"},{"type":"PACKAGE","url":"https://github.com/parse-community/parse-server"},{"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"}],"affected":[{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.0.0"},{"fixed":"9.5.2-alpha.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-7ch5-98q2-7289/GHSA-7ch5-98q2-7289.json"}},{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.6.16"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-7ch5-98q2-7289/GHSA-7ch5-98q2-7289.json"}}],"schema_version":"1.9.0","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"}]}
