AI Security Review
scanned 5d ago · by lpm-firewall-aiNo confirmed malicious attack surface. The package is a browser toolbar bundle that loads its SDK, calls Superflow/Velt/Firebase/Google endpoints, and uses browser storage for product state.
Static reason
One or more suspicious static signals were detected.
Trigger
Runtime use in a browser page importing or loading the toolbar script
Impact
Expected product telemetry/auth/storage behavior; no install-time or host compromise behavior identified
Mechanism
Browser custom element toolbar with package-aligned SDK/network calls
Rationale
Static inspection shows a bundled browser toolbar with expected third-party SDK loading and service calls, but no lifecycle hooks, system access, credential theft, persistence, destructive behavior, or agent-control mutation. Scanner hits are explained by browser/Firebase/Superflow functionality rather than a concrete malicious chain.

Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for block
- superflow.js dynamically injects Velt SDK scripts from cdn.velt.dev or staging/dev Google Cloud Run hosts at runtime.
- superflow.js contains bundled Firebase/Auth code reading process.env.t and __FIREBASE_DEFAULTS__, matching scanner env/cookie hints.
- superflow.js stores toolbar/session state in browser localStorage/sessionStorage and exposes window.Superflow methods.
Evidence against
- package.json has no preinstall/install/postinstall hooks and main is superflow.js only.
- No child_process, fs writes, native/binary loading, npm lifecycle mutation, or AI-agent control-surface writes found.
- Network endpoints are aligned with Superflow/Velt/Firebase/Google browser toolbar functionality.
- The high-secret-looking values appear to be bundled public client identifiers/config constants, not credential harvesting or exfiltration logic.
- superflow.min.js is a minified/browser build counterpart of superflow.js.
