Description
TDuck survey form through 6.0 fails to enforce form fill-in restrictions on the authenticated submission endpoint POST /user/form/data/create. Authenticated attackers who know a form's key can submit unlimited entries to any form, bypassing publish status, time window, quota, and per-IP restrictions to falsify collected results.
