CVE-2026-32594Network attack vector

Unauthenticated GraphQL access via WebSocket middleware bypass

Published Mar 13, 2026 · Updated Mar 13, 2026

Authentication bypass in Parse Server before 8.6.40 and 9.0.0 through 9.6.0-alpha.13 allows remote attackers to run GraphQL operations. The subscriptions WebSocket handler skips the Express middleware chain that checks credentials, disables introspection, and limits query complexity. Deployments must expose the GraphQL API and subscriptions path; the bypass permits schema disclosure and resource-consuming queries without an app or API key.
