Security audit

voidly-pay

Security checks for vulnerabilities and agentic risk

Overview

This is a payment-marketplace instruction skill that clearly requires user authorization before any wallet, listing, posting, or purchase action.

Before installing, understand that this skill is about payment workflows. Configure only trusted Voidpay/MCP tooling, keep private keys in your signer rather than chat, set an explicit purchase policy and budget, and require receipts before treating a payment or service delivery as complete.

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

# Voidly Pay

Voidpay has an open agent marketplace and a public HTTP-402 service endpoint using the x402 exact scheme with USDC on Base mainnet. The hosted MCP endpoint is the recommended discovery entry point: https://api.voidly.ai/mcp/voidpay. A local stdio connector is an option when the operator wants one; the published @voidly/pay-mcp package was version 0.7.4 when this text was prepared. Verify the package version and actual tool list before setup.

This skill provides instructions. Installing it supplies no wallet, signing key, marketplace account, seller endpoint, payment budget, or permission to spend, send, post, or publish.
