CVE-2026-47127Public exploitNetwork attack vectorHinoki check available

Premium entitlement bypass via unchecked Stripe session

Published Aug 7, 2026 · Updated Aug 7, 2026

Authorization bypass in Ghostfolio before 3.4.0 allows remote authenticated users to obtain a one-year Premium subscription without payment. The createSubscriptionViaStripe service retrieves a caller-supplied Checkout Session ID and creates the subscription without checking its payment or completion status. Exploitation requires an account and an enabled subscription feature; it unlocks subscription-gated features and records an unpaid entitlement as paid.
