Security checks for vulnerabilities and agentic risk

Overview

The skill provides paid media processing with disclosed uploads, payment approval, and controls against duplicate charges.

Use only media you are comfortable sending to external storage and processing services, since deletion timing is unspecified. Confirm each price, recipient, and wallet authorization before paying. Have an authorized maintainer review and preferably pin the payment dependency version. This review covers the bundled instructions, not the remote service or downloaded payment software.

A.I.G

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

Finding

The recommended installation command uses npx -y @alipay/agent-payment@latest install, allowing a mutable package release to execute code with the installer's privileges without an interactive installation confirmation. A compromised upstream release could expose payment credentials or local data; requiring an authorized maintainer and prohibiting automatic installation reduces exposure but does not eliminate this supply-chain risk. Although the finding labels this an MCP server reference, the actual issue is an unpinned CLI installation.
