NewCVE-2026-50008 (opens in a new tab)How to fix?
Upgrade parse-server to version 9.9.1-alpha.3 or higher.
Overview
parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js.
Affected versions of this package are vulnerable to Incorrect Authorization through the handleBatch request dispatcher in the batch request handling code. An attacker can reach disallowed REST endpoints by sending a /1/batch request whose sub-requests target blocked paths, allowing unauthorized object creation, modification, or retrieval through routes that operators intended to restrict.
Workarounds
- If you use
routeAllowListand havebatchallowlisted, explicitly add every inner REST route you intend to reach through/1/batchtorouteAllowListas well, for examplerouteAllowList: ['batch', 'classes/Public.*', 'functions/allowedFunction']. This prevents/batchsub-requests from reaching disallowed routes.
