Technical Analysis
SurveyKing prior to version 1.13.0 contains a missing authorization vulnerability in the GET /api/public/preview/{attachmentId} endpoint. Attackers who know or can derive time-ordered snowflake file IDs can bypass shared, owner, and project access checks in FileServiceImpl.loadFile, allowing unauthorized download of private survey attachments and respondent uploads. This vulnerability is remotely exploitable without authentication but requires high attack complexity. The vendor provides a patch, and since SurveyKing is a cloud service, remediation is managed by the vendor.
Potential Impact
Unauthenticated attackers can access and download private files stored in SurveyKing, including sensitive survey attachments and respondent uploads, potentially leading to data exposure. The vulnerability bypasses multiple layers of access control, compromising confidentiality of stored data.
Mitigation Recommendations
A patch is available for SurveyKing version 1.13.0 and later. Since SurveyKing is a cloud-hosted service, the vendor manages remediation server-side. Users should ensure they are using version 1.13.0 or later or confirm with the vendor that the service has been updated to address this vulnerability.
