Why It Matters
Analysis dossierWhy It Matters
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.

Suggested hunting (rule-based inference)
SecOps Signal recommendation (rule-based inference). These steps are hunting hypotheses from the vulnerability class; they do not state or imply that exploitation occurred here or anywhere.
Matched authorization-bypass (CWE-862); network-unauthenticated (CVSS AV:N, CVSS PR:N, CVSS UI:N)
Exposure
- Locate affected authorization controls and verify deployed versions.Telemetry: Application inventory · The source must identify the affected control. · Rule authorization-bypass
- Identify devices reporting this CVE and note which expose the affected service to untrusted networks.Telemetry: DeviceTvmSoftwareVulnerabilities · A network-reachable, no-privilege vector makes internet-facing instances the first exposure question. · Rule network-unauthenticated
Exploitation evidence
- Review privileged operations performed by unexpected users on affected deployments.Telemetry: Application audit logs · Authorization anomalies can support a targeted hunt. · Rule authorization-bypass

Exploitation evidence
- Review inbound connections to the affected service from unexpected sources since the advisory date.Telemetry: DeviceNetworkEvents · Hunting hypothesis from the CVSS vector; it does not show that exploitation occurred. · Rule network-unauthenticated
Response
- Confirm the vendor mitigation and recheck access decisions.Telemetry: Application audit logs · Access testing verifies the local fix. · Rule authorization-bypass
