{"cve":"CVE-2026-29182","nvd":{"published":"2026-03-06T21:16:15.137","modified":"2026-06-17T10:29:44.097","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 8.6.4 and 9.4.1-alpha.3, Parse Server's readOnlyMasterKey option allows access with master-level read privileges but is documented to deny all write operations. However, some endpoints incorrectly accept the readOnlyMasterKey for mutating operations. This allows a caller who only holds the readOnlyMasterKey to create, modify, and delete Cloud Hooks and to start Cloud Jobs, which can be used for data exfiltration. Any Parse Server deployment that uses the readOnlyMasterKey option is affected. Note than an attacker needs to know the readOnlyMasterKey to exploit this vulnerability. This issue has been patched in versions 8.6.4 and 9.4.1-alpha.3.","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-863"],"references":["https://github.com/parse-community/parse-server/releases/tag/8.6.4","https://github.com/parse-community/parse-server/releases/tag/9.4.1-alpha.3","https://github.com/parse-community/parse-server/security/advisories/GHSA-vc89-5g3r-cmhh"],"products":["parseplatform:parse-server"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-29182","score":0.00428,"percentile":0.37054,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-vc89-5g3r-cmhh","url":"https://osv.dev/vulnerability/GHSA-vc89-5g3r-cmhh","summary":"Parse Server's Cloud Hooks and Cloud Jobs bypass `readOnlyMasterKey` write restriction","modified":"2026-03-16T03:04:54.913640Z","packages":[{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":[">=9.0.0 <9.4.1-alpha.3"],"fixed":["9.4.1-alpha.3"]},{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":["<8.6.4"],"fixed":["8.6.4"]}]}],"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).
