CVE-2025-11439Public exploitNetwork attack vector

Integration data disclosure via permissive view policy

Published Oct 8, 2025 · Updated Oct 8, 2025

Missing authorization in OpnForm 1.9.0 through 1.9.3 allows remote authenticated users to read form integration data. FormIntegrationsController and FormIntegrationsEventController authorize index requests with the form view policy instead of the update policy. A read-only workspace member can reach the integrations and events endpoints, exposing configuration and event data without modification rights.
