Cn Emoji Tool

Security checks for vulnerabilities and agentic risk

Overview

This is a small local Chinese emoji lookup and text-conversion tool with no evidence of hidden network access, persistence, credential use, or destructive behavior.

Install this if you want a local Chinese-language emoji helper. Be aware that the documentation and command output are primarily Chinese, and the README includes promotional AISoBrand links, but the reviewed code does not contact those sites or perform hidden actions.

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
Category
Not specified by scanner
Confidence
96% confidence
Finding

The file’s natural-language instructions and usage guidance are presented only in Chinese, which imposes a specific language on users without any opt-in or alternative locale support. Under the policy, language constraints should either offer user choice or be explicitly documented as a justified region-specific limitation.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
92% confidence
Finding

This Python skill contains natural-language descriptions, docstrings, error messages, and CLI help entirely in Chinese, including the main tool description and argument help text. Under the policy rule for language or locale constraints, this is a violation because the skill imposes a specific language without documenting user choice or opt-in.
