AI Security Review
scanned 5d ago · by lpm-firewall-aiThe flagged callback resolves to ARCY’s own API, but the SDK also collects and sends browser measurement events before consent unless the browser signals Do Not Track or Global Privacy Control. Because the README does not disclose this pre-consent behavior, this is suspicious runtime telemetry rather than a clear malicious attack.
Static reason
One or more suspicious static signals were detected.
Trigger
A site calls arcy.init() while consent is undecided and the browser does not signal Do Not Track or Global Privacy Control.
Impact
Visitor page routes and interaction events may be collected before consent; the package documents consent controls but not this pre-consent collection.
Mechanism
The collector binds event listeners and queues measurement events, which it posts to ARCY’s measurement endpoint.
AI rationale
The flagged callback resolves to ARCY’s own API, but the SDK also collects and sends browser measurement events before consent unless the browser signals Do Not Track or Global Privacy Control. Because the README does not disclose this pre-consent behavior, this is suspicious runtime telemetry rather than a clear malicious attack.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- When consent has not been granted, the collector still starts if measurement is allowed by the browser’s privacy signals.
- Pre-consent measurement can include page loads, navigation, clicks, form submissions, and field interactions.
- Measurement events include the current route, locale, device class, and event payload.
- The measurement transport posts events to ARCY’s own API.
- The README describes the consent flow but does not disclose that measurement can occur before consent.
Evidence against
- Network traffic is directed to the package’s own ARCY API.
- The README provides a consent API and says refusal stops collection.
