CVE-2025-31481Public exploitNetwork attack vector

Unauthenticated entity disclosure via Relay node queries

Published Apr 3, 2025 · Updated Apr 8, 2025

Incorrect authorization in API Platform Core allows remote attackers to read protected entities through GraphQL Relay node queries. ResolverFactory substitutes an empty Query operation for Relay node requests, so the configured operation security expression is never evaluated. The API must expose GraphQL's default node field and protect an entity with the security attribute; the bypass discloses that entity without authentication.
