{"cve":"CVE-2026-50008","nvd":{"published":"2026-06-12T19:16:29.187","modified":"2026-10-26T11:10:00.157","status":"Deferred","description":"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.","cvss_v4":{"vector":"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","score":6.9},"cvss_v3":null,"cwes":["CWE-863"],"references":["https://github.com/parse-community/parse-server/pull/10482","https://github.com/parse-community/parse-server/security/advisories/GHSA-p84r-h6rx-f2xr"],"products":[],"source":"nvd","synced_at":"2026-10-26T11:33:08.859761529+00:00"},"epss":{"cve":"CVE-2026-50008","score":0.00343,"percentile":0.2755,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-p84r-h6rx-f2xr","url":"https://osv.dev/vulnerability/GHSA-p84r-h6rx-f2xr","summary":"parse-server: Server option routeAllowList is bypassable through batch sub-requests","modified":"2026-06-19T19:56:23.310969568Z","packages":[{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":[">=9.8.0 <9.9.1-alpha.3"],"fixed":["9.9.1-alpha.3"]}]}],"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).
