Security checks for vulnerabilities and agentic risk

Overview

This is a plain US stock analysis prompt skill with no executable code, persistence, credential handling, or hidden data access.

Installers should understand that this skill can produce investment research and optional trade-plan structure, but it explicitly requires sourcing, risk framing, no fabricated data, and a non-advice disclaimer. Users should still verify market data and make their own financial decisions.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding
The markdown declares `language: en-US` as a hard setting, while the rest of the skill does not provide any opt-in or alternative locale handling. Under the policy, fixed language or locale constraints should either be optional for the user or clearly justified as region-specific beyond market coverage alone.
