{"cve":"CVE-2026-34784","nvd":{"published":"2026-03-31T20:16:29.490","modified":"2026-07-24T20:10:00.147","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 8.6.71 and 9.7.1-alpha.1, file downloads via HTTP Range requests bypass the afterFind(Parse.File) trigger and its validators on storage adapters that support streaming (e.g. the default GridFS adapter). This allows access to files that should be protected by afterFind trigger authorization logic or built-in validators such as requireUser. This issue has been patched in versions 8.6.71 and 9.7.1-alpha.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-285"],"references":["https://github.com/parse-community/parse-server/commit/053109b3ee71815bc39ed84116c108ff9edbf337","https://github.com/parse-community/parse-server/commit/a0b0c69fc44f87f80d793d257344e7dcbf676e22","https://github.com/parse-community/parse-server/pull/10361","https://github.com/parse-community/parse-server/pull/10362","https://github.com/parse-community/parse-server/security/advisories/GHSA-hpm8-9qx6-jvwv"],"products":["parseplatform:parse-server"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-34784","score":0.00393,"percentile":0.3343,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hpm8-9qx6-jvwv","url":"https://osv.dev/vulnerability/GHSA-hpm8-9qx6-jvwv","summary":"Parser Server's streaming file download bypasses afterFind file trigger authorization","modified":"2026-04-06T15:27:18.137809623Z","packages":[{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":[">=9.0.0 <9.7.1-alpha.1"],"fixed":["9.7.1-alpha.1"]},{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":["<8.6.71"],"fixed":["8.6.71"]}]}],"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).
