AI Security Review
scanned 5d ago · by lpm-firewall-aiThe flagged authorization uses a WalletLink session ID and secret and is directed to Coinbase WalletLink endpoints for wallet relay operations. The package exposes a checkout component, and its manifest has no install-time hook that would trigger unrelated collection.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
WalletLink relay communication when the checkout wallet flow is used.
Impact
No unrelated credential collection, external exfiltration, or unrequested account action was identified.
Mechanism
The SDK builds Basic authorization from its WalletLink session ID and secret and sends requests to the configured WalletLink service.
AI rationale
The flagged authorization uses a WalletLink session ID and secret and is directed to Coinbase WalletLink endpoints for wallet relay operations. The package exposes a checkout component, and its manifest has no install-time hook that would trigger unrelated collection.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest describes a web checkout SDK for crypto payments.
- The only lifecycle script is prepublishOnly, which restricts publishing to CI; it is not an install hook.
- The entry module imports the checkout component, which loads the wallet engine when its engine-loading method runs.
- The flagged Authorization value is constructed from a WalletLink session ID and session secret.
- The relay uses Coinbase WalletLink and related Coinbase endpoints.
