Description
TDuck Survey Form through 5.3 contains a missing authorization vulnerability that allows any authenticated user to read other owners' raw form settings via GET /user/form/setting/{key}. Attackers can supply the 8-character form key from a public fill link to obtain the form write password, owner notification e-mail, and WeChat openIds.
