CVE-2026-50008
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.
