What it is

SurveyKing before 1.13.0 contains a missing authorization vulnerability that allows unauthenticated attackers to download any stored file by id through GET /api/public/preview/{attachmentId}. Attackers who know or derive time-ordered snowflake file ids can bypass shared, owner, and project checks in FileServiceImpl.loadFile to read private survey attachments and respondent uploads.
