CVE-2026-92099Network attack vectorHinoki check available

Unauthenticated alias squatting via unchecked queryId

Published Sep 19, 2026 · Updated Sep 19, 2026

Improper access control in WPGraphQL Smart Cache before 2.3.2 allows remote attackers to register arbitrary persisted queries. The request handler saves a caller-supplied query and queryId before authorization or validation, letting the identifier become an alias. No authentication or user interaction is required; an attacker can preempt aliases expected by the site frontend and alter persisted-query behavior.
