Security checks for vulnerabilities and agentic risk

Overview

This is a public stock-analysis guidance skill with no code, persistence, credential use, or hidden actions, though users should treat its financial outputs as informational rather than guaranteed advice.

Before installing, expect the skill to browse public finance sites and produce strongly formatted stock reports, possibly in Chinese-style labels. Verify any prices, catalysts, and trading levels independently because market data changes quickly and the bundled reference examples may become stale.

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

Natural-Language Policy Violations

Medium
Confidence
96% confidence
Finding
The skill content strongly prescribes Chinese-language behavior and output formatting without any indication that this should be conditional on the user's language preference. This can override user intent, reduce accessibility, and cause the agent to ignore higher-level user communication needs, which is a genuine policy and safety concern for agent skills.
