How to fix?

Upgrade parse-server to version 8.6.40, 9.6.0-alpha.14 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 Authentication for Critical Function in the createSubscriptions process. An attacker can execute unauthorized GraphQL operations, access schema introspection, and bypass query complexity limits by connecting to the WebSocket endpoint without valid credentials.

Workaround

This vulnerability can be mitigated by blocking WebSocket upgrade requests to the GraphQL subscriptions path (by default /subscriptions) at the network level, such as using a reverse proxy or load balancer rule.
