This issue affects an unknown function of the component GraphQL WebSocket Endpoint. The manipulation with an unknown input leads to a missing authentication vulnerability.

The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 8.6.40 and 9.6.0-alpha.14, the GraphQL WebSocket endpoint for subscriptions does not pass requests through the Express middleware chain that enforces authentication, introspection control, and query complexity limits. An attacker can connect to the WebSocket endpoint and execute GraphQL operations without providing a valid application or API key, access the GraphQL schema via introspection even when public introspection is disabled, and send arbitrarily complex queries that bypass configured complexity limits. This vulnerability is fixed in 8.6.40 and 9.6.0-alpha.14.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-32594 since 03/12/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.
