gatsby-core-theme@44.35.5
Gatsby Theme NPM Package
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has no lifecycle hook, but its active SSR tracking path can send full visitor cookies to an unrestricted operator-configured endpoint. This warrants a warning for conditional credential exposure, not a publication block.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A request to a generated tracking page while IS_TRACKING_SSR is true.
Impact
A deployment operator can configure a destination that receives visitor cookies and tracking identifiers, creating conditional credential and privacy exposure.
Mechanism
getServerData passes inbound headers to getAffiliateLink, which parses and serializes cookies into a query string sent to GATSBY_TRACKING_API_URL.
AI rationale
The package has no lifecycle hook, but its active SSR tracking path can send full visitor cookies to an unrestricted operator-configured endpoint. This warrants a warning for conditional credential exposure, not a publication block.
Evidence
gatsby-node.mjssrc/components/app-tracker-ssr.jssrc/helpers/tracker.mjs
Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The manifest defines test and Storybook commands, with no install lifecycle hook.
- When SSR tracking is enabled, the tracking page passes request headers and URL to getAffiliateLink.
- The tracker parses all request cookies, serializes them into query parameters, and fetches an endpoint selected by GATSBY_TRACKING_API_URL without a destination allowlist.
Evidence against
- The risky forwarding path is conditional on SSR tracking configuration and page generation, not package installation or import.
- Newsletter collection sends values entered into that form to a fixed subscription service; it is user-triggered.
