AI Security Review
scanned 5d ago · by lpm-firewall-aiThe flagged authorization flow uses a Link session’s own credentials for event requests to its configured API, and checkout initialization is caller-triggered. The manifest contains no install hook that would run this behavior automatically.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Checkout initialization follows a caller’s init or initExistingSession call.
Impact
No unrelated credential collection, install-time exfiltration, or unrequested account action was identified.
Mechanism
The Link client derives authorization from its session ID and secret and sends it to its configured linkAPIUrl for event operations.
AI rationale
The flagged authorization flow uses a Link session’s own credentials for event requests to its configured API, and checkout initialization is caller-triggered. The manifest contains no install hook that would run this behavior automatically.
Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes dist/lydian.js as the package entry and defines only a prepublishOnly guard, not an install hook.
- The entry module imports the SDK chunk; checkout initialization validates the transaction or existing session before initializing the checkout.
- The Link client builds Basic authorization from a session ID and secret, then uses it for event requests to its configured linkAPIUrl.
- The SDK’s exposed init and initExistingSession functions invoke checkout initialization when called.
