Fattmerchant

Security checks across malware telemetry and agentic risk

Overview

This appears to be a legitimate Fattmerchant integration, but it gives an agent broad authenticated access to a payment-processing account with weak safety scoping for changes.

Install only if you trust the Membrane workflow and are prepared to supervise Fattmerchant operations. Use least-privilege account access where possible, confirm every charge, refund, deletion, user or role change, and direct proxy request before execution, and revoke the Membrane connection when no longer needed.

Missing User Warnings

Medium

Confidence: 92% confidence
Finding: The skill explicitly documents a generic proxy mechanism that supports arbitrary API paths and state-changing methods like POST, PUT, PATCH, and DELETE without any embedded warning, approval step, or guardrail around destructive operations. In a payment-processing context, this increases the chance an agent could modify financial records, customers, invoices, or terminal settings through free-form requests with insufficient user awareness.
