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 Uncaught Exception via a file pointer object without a URL submitted in an object write request. When RestWrite processes an incoming object containing a __type: 'File' entry that has no url field, the server crashes due to an unhandled error path in expandFilesInObject in FilesController.js, causing a denial of service. An unauthenticated remote attacker can trigger this crash by sending a write request with a file pointer that omits the URL.
