Market Signal Fusion

Security checks for vulnerabilities and agentic risk

Overview

This is an instruction-only market-analysis skill whose web, market-data, and social-sentiment use is disclosed and aligned with its stock-analysis purpose.

Before installing, treat outputs as market analysis rather than personalized financial advice, verify prices and metrics independently, and be aware that configured web, market-data, or social-data tools may send tickers and related context to external services.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • System Prompt LeakageDirect Leakage, Indirect Extraction, Tool-Based Exfiltration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Finding

The skill provides stock picks, valuation ranges, entry zones, stops, and take-profit plans while deferring the financial-risk disclaimer to the very end. This can cause users or downstream agents to treat the output as actionable investment advice without seeing limitations, uncertainty, or suitability warnings before consuming the recommendations.

Finding

This markdown file describes the skill as working best with browser, search, market-data API, and optional Reddit/social-data tools, which implies network access and possible transmission of user queries or system-derived context to external services. The README does not include any user-facing warning about privacy, external requests, or data handling, so the behavior lacks disclosure under the markdown warning criterion.
