Form Widget
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe widget automatically sends unfinished form answers to its configured events endpoint when the widget closes or the page unloads. Because the README documents attribution tracking but not this partial-answer collection, treat it as undisclosed runtime telemetry and warn users.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The user closes the widget or unloads the page while a form is incomplete.
Impact
The configured API receives answers the user may not have submitted; these answers may contain personal information.
Mechanism
The widget sends current partial form values and metadata in a `partial_data` event to `/cms/widget/events` on the configured API origin.
AI rationale
The widget automatically sends unfinished form answers to its configured events endpoint when the widget closes or the page unloads. Because the README documents attribution tracking but not this partial-answer collection, treat it as undisclosed runtime telemetry and warn users.

configured API origin: /cms/widget/events
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- Closing the widget can send current form values as `partialData` with a `widget_close` reason.
- A `beforeunload` handler sends partial form data with a `close_tab` reason.
- The data is sent as a `partial_data` event with browser and session metadata to `/cms/widget/events` on the configured API origin; the beacon uses the widget key.
- The README documents attribution parameter tracking but does not mention collection of unfinished form answers.
Evidence against
- The package is a multi-step form widget, so sending abandoned answers to its configured API could support form recovery or analytics.
- Beacon tracking is skipped in demo mode or when no widget key is configured.
- The `prepare` script runs the package’s Rollup build; no install-time data collection was identified.
