{"cve":"CVE-2026-33539","nvd":{"published":"2026-03-24T19:16:54.853","modified":"2026-06-17T10:37:40.660","status":"Analyzed","description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.59 and 9.6.0-alpha.53, an attacker with master key access can execute arbitrary SQL statements on the PostgreSQL database by injecting SQL metacharacters into field name parameters of the aggregate $group pipeline stage or the distinct operation. This allows privilege escalation from Parse Server application-level administrator to PostgreSQL database-level access. Only Parse Server deployments using PostgreSQL are affected. MongoDB deployments are not affected. This issue has been patched in versions 8.6.59 and 9.6.0-alpha.53.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","score":7.2},"cwes":["CWE-89"],"references":["https://github.com/parse-community/parse-server/commit/03249f9bf5b8783c8b848f84dab791ff0b761b8c","https://github.com/parse-community/parse-server/commit/bdddab5f8b61a40cb8fc62dd895887bdd2f3838e","https://github.com/parse-community/parse-server/pull/10272","https://github.com/parse-community/parse-server/pull/10273","https://github.com/parse-community/parse-server/security/advisories/GHSA-p2w6-rmh7-w8q3"],"products":["parseplatform:parse-server"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33539","score":0.0047,"percentile":0.40634,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p2w6-rmh7-w8q3","url":"https://osv.dev/vulnerability/GHSA-p2w6-rmh7-w8q3","summary":"Parse Server has SQL Injection through aggregate and distinct field names in PostgreSQL adapter","modified":"2026-03-27T22:03:50.528822Z","packages":[{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":[">=9.0.0 <9.6.0-alpha.53"],"fixed":["9.6.0-alpha.53"]},{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":["<8.6.59"],"fixed":["8.6.59"]}]}],"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).
