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

• Third-party content exposure detected (medium risk: 0.30). The required workflow interacts with the Coupa platform via Composio/Rube MCP, which can ingest outsider-authored free text from Coupa data records such as invoices, purchase orders, or supplier comments.

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

• Potentially malicious external URL detected (high risk: 0.70). The skill instructs the agent to configure an external Model Context Protocol server URL at runtime (https://rube.app/mcp), which constitutes an unverifiable external runtime dependency of unknown/third-party provenance.

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

• Direct money access detected (medium risk: 0.30). The skill automates Coupa procurement and expense tasks (such as invoices and purchasing) through the Rube MCP/Composio toolkit. Coupa handles billing, invoicing, and financial procurement operations, representing indirect financial operations (creating bills/invoices, submitting billable usage or purchase requisitions for downstream handling).
