{"id":"CVE-2026-50008","summary":"Parse Server: Server option routeAllowList is bypassable through batch sub-requests","details":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. From version 9.8.0 to before version 9.9.1-alpha.3, the routeAllowList server option restricts external client access to a configured list of REST API routes. The check is only enforced as Express middleware against the outer HTTP request URL, so the /batch handler dispatches each sub-request to the internal router without re-running the allow-list check. An external caller whose outer route matches batch can issue batch sub-requests to any REST API route that the operator omitted from the allow-list. Authentication, ACL, CLP, and other inner-route authorization controls still apply — only the operator-configured route firewall is bypassed. This issue has been patched in version 9.9.1-alpha.3.","aliases":["BIT-parse-2026-50008","GHSA-p84r-h6rx-f2xr"],"modified":"2026-07-08T08:09:43.126804093Z","published":"2026-06-12T18:22:44.188Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50008.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50008.json"},{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-p84r-h6rx-f2xr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50008"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/pull/10482"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/parse-community/parse-server","events":[{"introduced":"7c3b43d2633cfe96a5bd1e853b84fa34846a03bd"},{"fixed":"1e0d6cee9bd898e418dff9eab9211599d5f77abd"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"9.8.0"},{"fixed":"9.9.1-alpha.3"},{"introduced":"0"}]}}],"versions":["9.9.1-alpha.2","9.9.1-alpha.1","9.9.0","9.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-50008.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
