Confidential-data disclosure via unvalidated GraphiQL request destination
Published Aug 27, 2026 · Updated Aug 27, 2026
Information exposure in affected Spring for GraphQL releases allows remote attackers to leak confidential data through a malicious GraphiQL URL. The bundled page accepts an attacker-controlled request destination without enforcing the application's origin before initializing its GraphQL fetcher. Exposure requires an enabled, network-accessible GraphiQL endpoint and a victim with an active session to follow the link; the reported consequence is confidential-data disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
