NewCVE-2026-30850 (opens in a new tab)How to fix?
Upgrade parse-server to version 8.6.9, 9.5.0-alpha.9 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 Missing Authorization in the GET /files/:appId/metadata/:filename endpoint due to the lack of enforcement of beforeFind and afterFind triggers. An attacker can gain unauthorized access to file metadata by sending requests to this endpoint, bypassing intended access control mechanisms.
##Workaround
This vulnerability can be mitigated by disabling the metadata endpoint by overriding the route with a middleware that rejects all requests.
