Agent ToMerchant

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed merchant-payment API guide, with expected credential and webhook-secret handling for receiving payments.

Install only if you intend to let an agent manage SynapseAI merchant receiving workflows. Keep the bearer token and webhook secret private, verify webhook signatures, and be aware that the skill can create wallets/payment links, expose public payment pages, configure callback URLs, and persist merchant status in the provider account.

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Missing User Warnings

Low

Confidence: 77% confidence
Finding: This markdown file documents returning a webhook `secret` and only briefly says to keep it safe. Because the skill description includes handling of a credential-like value that will be used to verify signatures, a clearer user warning about not logging, exposing, or sharing the secret would better address privacy and integrity risks.
