{"cve":"CVE-2026-30966","nvd":{"published":"2026-03-10T21:16:48.980","modified":"2026-06-17T10:33:14.413","status":"Analyzed","description":"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.7 and 8.6.20, Parse Server's internal tables, which store Relation field mappings such as role memberships, can be directly accessed via the REST API or GraphQL API by any client using only the application key. No master key is required. An attacker can create, read, update, or delete records in any internal relationship table. Exploiting this allows the attacker to inject themselves into any Parse Role, gaining all permissions associated with that role, including full read, write, and delete access to classes protected by role-based Class-Level Permissions (CLP). Similarly, writing to any such table that backs a Relation field used in a pointerFields CLP bypasses that access control. This vulnerability is fixed in 9.5.2-alpha.7 and 8.6.20.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:L","score":10.0},"cwes":["CWE-284"],"references":["https://github.com/parse-community/parse-server/releases/tag/8.6.20","https://github.com/parse-community/parse-server/releases/tag/9.5.2-alpha.7","https://github.com/parse-community/parse-server/security/advisories/GHSA-5f92-jrq3-28rc"],"products":["parseplatform:parse-server"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-30966","score":0.00399,"percentile":0.3418,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5f92-jrq3-28rc","url":"https://osv.dev/vulnerability/GHSA-5f92-jrq3-28rc","summary":"Parse Server has role escalation and CLP bypass via direct `_Join` table write","modified":"2026-03-14T03:41:13.204459Z","packages":[{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":[">=9.0.0-alpha.1 <9.5.2-alpha.7"],"fixed":["9.5.2-alpha.7"]},{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":["<8.6.20"],"fixed":["8.6.20"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
