Security checks for vulnerabilities and agentic risk

Overview

This earnings-research skill uses the disclosed Finskills API for its stated purpose and does not include code, persistence, or hidden authority.

Before installing, be comfortable sharing the tickers, date ranges, and earnings-research context you ask about with Finskills, and use an API key with only the access level needed for the data you want.

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 skill instructs the agent to send user-provided stock symbols and related earnings-research queries to the external Finskills API, but it does not clearly warn the user that their inputs will be transmitted to a third-party service. This creates a privacy and transparency issue: even if symbols are not highly sensitive by themselves, user investment interests, timing, and query context can reveal confidential research intent or trading focus.
