AI Security Review
scanned 5d ago · by lpm-firewall-aiThe widget automatically sends visitor measurement events when consent is absent or refused, as long as Do Not Track and Global Privacy Control are not set. This conflicts with the documented consent behavior, so the package warrants a warning for runtime telemetry.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The application initializes the widget; measurement listeners start automatically when the browser does not signal Do Not Track or Global Privacy Control.
Impact
Visitor behavior and page context may be collected despite the documented consent flow or a refusal. The inspected field-description code omits entered field values.
Mechanism
The measurement path is gated by browser privacy signals rather than the stored consent choice. It queues page, navigation, interaction, form, field, and other whitelisted events for transmission to the first-party API.
AI rationale
The widget automatically sends visitor measurement events when consent is absent or refused, as long as Do Not Track and Global Privacy Control are not set. This conflicts with the documented consent behavior, so the package warrants a warning for runtime telemetry.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- Measurement is enabled unless the browser signals Do Not Track or Global Privacy Control; this check does not consult the visitor’s consent choice.
- When consent is absent, capture sends events through a separate measurement transport for a whitelist that includes page, navigation, click, form, and field events.
- Startup binds measurement listeners and records a page-load event before consent when measurement is allowed.
- The README says one consent covers ARCY’s collection and that refusing stops collection, which conflicts with the pre-consent measurement path.
- The measurement and telemetry transports use the package’s first-party api.arcyai.com endpoints.
- Field descriptions include validity and a textless form fingerprint, not the field’s entered value.
Evidence against
- The README documents a consent API and says refusal stops collection.
- The identified endpoints belong to arcyai.com, and the inspected field-description code does not include entered field values.
