AI Security Review
scanned 1d ago · by lpm-firewall-aiInitialization sends runtime telemetry to the configured API and the browser Origin header identifies the site using the SDK. The request is described in source, but no visible opt-out was found; the flagged account-hijack behavior was not confirmed.
Static reason
No blocking static signals were detected.
Trigger
SDK init, at most once daily per project and browser.
Impact
The service learns which site uses the SDK. This identifying runtime telemetry has no visible opt-out, so it warrants a warning.
Mechanism
After a five-second delay, POSTs project and SDK metadata to the configured API base; the browser also supplies the site's Origin header.
AI rationale
Initialization sends runtime telemetry to the configured API and the browser Origin header identifies the site using the SDK. The request is described in source, but no visible opt-out was found; the flagged account-hijack behavior was not confirmed.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Initialization sends a once-daily `/ingest/hello` POST to the configured API base, using the project API key.
- The hello request relies on the browser Origin header, which identifies the site using the SDK.
- The hello payload includes project ID, SDK version, and whether user identification and context are configured.
- The package describes this request as reporting which site has the SDK installed, but provides no visible opt-out.
Evidence against
- The package is a browser bug-reporting SDK, and its report and sign-in requests use the configured API base.
- The inspected issue-following action is initiated by a user click; no account mutation was identified during initialization.
- The hello payload contains project and configuration metadata rather than credentials, files, or report contents.
