Published Sep 23, 2026 · Updated Sep 23, 2026

Authorization bypass in Verbb Formie 2 before 2.2.23 and 3.0.0 through 3.1.30 allows remote authenticated users to read sent emails. SentNotificationsController::actionGetResendModalContent accepts a request-supplied notification ID without checking sent-notification permission or object ownership. Any authenticated control-panel user able to invoke the action can enumerate IDs and read recipient headers and complete HTML bodies containing submitted form data.
