gatsby-core-theme@44.35.6
Gatsby Theme NPM Package
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is a real conditional credential-forwarding capability to an unrestricted configured endpoint, so it warrants a warning. The inspected manifest contains no lifecycle hook or other evidence of an automatic malicious installation chain.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A Gatsby request invoking the tracker page's getServerData function.
Impact
A deployer-configured endpoint can receive visitors' session or other cookie values in the request URL.
Mechanism
The tracker parses the Cookie header, adds the complete cookie object to URL parameters, and fetches GATSBY_TRACKING_API_URL.
AI rationale
This is a real conditional credential-forwarding capability to an unrestricted configured endpoint, so it warrants a warning. The inspected manifest contains no lifecycle hook or other evidence of an automatic malicious installation chain.
Evidence
src/components/app-tracker-ssr.jssrc/helpers/tracker.mjs
Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The server-side tracker receives each request's headers and URL.
- It parses the incoming Cookie header.
- It serializes all parsed cookies into tracking query parameters, including values not limited to its named analytics cookies.
- It sends those parameters to the unrestricted GATSBY_TRACKING_API_URL configuration value.
Evidence against
- The manifest has no preinstall, install, or postinstall script.
- The outgoing request forwards only selected Cloudflare headers; the exposure is through the serialized cookie query parameter.
- The newsletter redirect occurs only after a user submits the form and the subscription service returns OK.
