Lifecycle Timeline
4Description
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.71 and 9.7.1-alpha.1, file downloads via HTTP Range requests bypass the afterFind(Parse.File) trigger and its validators on storage adapters that support streaming (e.g. the default GridFS adapter). This allows access to files that should be protected by afterFind trigger authorization logic or built-in validators such as requireUser. This issue has been patched in versions 8.6.71 and 9.7.1-alpha.1.
Analysis
Parse Server versions prior to 8.6.71 and 9.7.1-alpha.1 allow HTTP Range requests to bypass the afterFind trigger and its validators when downloading files from streaming-capable storage adapters like GridFS, enabling unauthorized access to protected files that should be restricted by authentication or authorization logic. This authentication bypass affects all deployments using affected versions with file protection policies enforced via afterFind triggers.
