Form Widget
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe widget silently sends partial form answers on page close, before the visitor explicitly submits the form. This is suspicious runtime data collection, although sending completed form data to the widget’s configured service is consistent with the package’s purpose.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A visitor closes or navigates away from a page while the widget has active form state.
Impact
Form answers may reach the widget service before the visitor submits the form; this is undisclosed runtime collection of user-provided data.
Mechanism
A beforeunload handler combines current form state and sends it in a partial_data beacon to the configured widget API origin’s /cms/widget/events endpoint.
AI rationale
The widget silently sends partial form answers on page close, before the visitor explicitly submits the form. This is suspicious runtime data collection, although sending completed form data to the widget’s configured service is consistent with the package’s purpose.
Evidence
dist/index.js
Network endpoints2
configured widget API origin + /cms/widget/eventsapi.xapp.ai
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- On tab close, the widget merges its current form state and submits it as `partialData` with the abandonment reason `close_tab`.
- The partial-data beacon packages that object as a `partial_data` event and sends it to the configured widget API origin at `/cms/widget/events`.
- The package manifest exposes a form-widget entry point; the observed data collection occurs in the widget’s runtime form flow.
Evidence against
- The package is described as a form widget, so transmitting form answers to its configured service is related to its purpose.
- The beacon requires a configured widget key and is suppressed in demo mode.
- The package’s only lifecycle script is a build command; no install-time data collection was identified.
