Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward portfolio-analysis skill that uses a Finskills API key and market-data endpoints, with no executable code, persistence, brokerage access, or trade execution.

Before installing, understand that you may be sharing sensitive portfolio details with your agent session. Provide cost basis only when you want total return or tax-aware context, and expect ticker symbols to be sent to Finskills for quote and profile data. This skill does not connect to brokerage accounts or execute trades.

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 README explicitly encourages users to provide full holdings and cost-basis information so the skill can process a portfolio, but it provides no privacy notice, data-handling explanation, or minimization guidance. Portfolio composition and cost basis are sensitive financial data; even if only quote endpoints are called, users are being prompted to disclose detailed financial information without clear warning about what is sent, stored, logged, or retained.
