MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (medium risk: 0.30). The skill’s runtime workflow ingests outsider-authored free text via the Shopify webhook HTTP request body (payload) in app/routes/webhooks.tsx, which can be attacker-controlled by triggering webhooks with malicious content.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.80). The skill recommends loading an unversioned remote script at runtime which executes code in clients — https://cdn.shopify.com/shopifycloud/app-bridge.js is included via a tag and is presented as the required way to get the latest App Bridge, so this URL is a runtime-executed external dependency.

MEDIUM W009: Direct money access capability detected (payment gateways, crypto, banking).

• Direct money access detected (high risk: 1.00). The skill includes explicit Billing API integration that creates subscription charges via a GraphQL mutation (appSubscriptionCreate), supplies plan amounts/currency, and programmatically redirects to a confirmation URL to complete approval. This is a specific, built-in financial operation (initiating charges/subscriptions) rather than a generic API or UI action.
