Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed paid stock-scanning skill description with financial-risk caveats to consider, but I found no hidden execution, persistence, credential access, or unsafe system behavior in the artifact.

Only install this if you understand the Chinese documentation and are comfortable with a paid stock-screening tool. Treat its scores, labels, and backtest examples as informational research, not financial advice; verify methodology, data freshness, payment terms, and risk disclaimers before trading or paying.

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 presents stock screening, scoring, action labels like buy/watch/hold, and backtest performance in a way that could reasonably be interpreted as investment guidance, yet it provides no disclaimer about financial risk or that outputs are informational rather than financial advice. In a paid trading-focused skill, this increases the chance that users will rely on the outputs to make real-money decisions and suffer losses.

Natural-Language Policy Violations

Finding

SQP-3 applies to all file types and includes language or locale policy violations. The description and major user-facing sections are presented in Chinese only, and the file does not indicate that the skill is region-specific or that users can opt into this language, which can amount to forcing a specific language without user choice.
