Network endpoint, low complexity, and any authenticated user suffices (PR:L); missing ownership check yields high integrity impact via data overwrite, with no confidentiality or availability effect.

Lifecycle Timeline
3DescriptionCVE.org
TDuck survey form through version 5.0 contains an authorization bypass vulnerability in the POST /user/form/data/update endpoint that allows authenticated users to overwrite other users' form submission data. Attackers can discover submission identifiers allocated in narrow ranges and modify arbitrary form responses containing personal data by sending update requests without ownership validation.
AnalysisAI
This is a genuine but bounded-priority integrity flaw: in TDuck Survey Form through version 5.0, any authenticated low-privilege user can overwrite other respondents stored form submissions by calling POST /user/form/data/update with a submission identifier that does not belong to them, because the endpoint performs no ownership validation (CWE-639). Confidentiality and availability are unaffected, so the realistic impact is corruption or falsification of collected survey data, including responses containing personal information, rather than data theft or denial of service. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated account on the TDuck survey platform (PR:L) - any low-privilege registered user qualifies; no admin role, user interaction, or non-default configuration is needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but bounded-priority integrity flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch or fixed version is identified in the provided references, so treat remediation as compensating-control work until TDuckCloud ships a fix beyond the 5.0 line; monitor the repository and issue 39 for a patched release and upgrade immediately when it appears. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, restrict access to POST /user/form/data/update to trusted roles and disable it if not business-critical, audit recent TDuck Survey Form submissions for unauthorized changes, and enable alerts for anomalous update requests. …
