Security audit

Cn Unicode Info

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small local Unicode lookup utility with no hidden persistence, network execution, or sensitive data access.

This appears safe to install for Unicode character inspection. Be aware that the skill documentation includes promotional Chinese-language links unrelated to the tool's core function; users who do not want promotional material may prefer that removed or localized, but it does not change the runtime behavior found here.

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 is primarily in English, but the closing promotional section switches to Chinese-only text. This can violate language/locale policy expectations because it forces a specific language on users without opt-in or justification that the skill is region-specific.
