AI Security Review
scanned 28d ago · by lpm-firewall-aiThe tracker actively forwards the complete incoming cookie object to an operator-configured endpoint, creating conditional credential exposure. The newsletter flow is consistent with signup behavior and does not append submitted identity fields to its success redirect.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A Gatsby server data request invokes the tracker.
Impact
Cookies may be exposed to the endpoint configured by the consuming site; the inspected code does not bind them to a fixed destination.
Mechanism
The tracker parses the request Cookie header, serializes the cookie object into tracking parameters, and sends them to the configured tracking API URL.
AI rationale
The tracker actively forwards the complete incoming cookie object to an operator-configured endpoint, creating conditional credential exposure. The newsletter flow is consistent with signup behavior and does not append submitted identity fields to its success redirect.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The server-side tracker parses the incoming Cookie header and places the parsed cookies into tracking parameters.
- The tracker serializes the full cookie object and sends the parameters to the operator-configured tracking API URL, without a destination allowlist in the inspected path.
- The SSR tracker invokes this logic while handling server data requests.
Evidence against
- The newsletter sends submitted signup fields to its signup endpoint; its redirect is gated on a successful response and does not append those fields.
- The manifest points to index.js and contains no install lifecycle hooks.
