Security audit

Cn Word Counter

Security checks for vulnerabilities and agentic risk

Overview

This is a simple local word-counting skill with no evidence of hidden access, persistence, credential use, network calls, or unsafe behavior.

This skill appears safe for its stated purpose. Before installing, note that the documentation is Chinese-only and includes promotional external links, though those links are not used by the runtime script. Avoid passing highly sensitive text on the command line if shell history exposure matters in your environment.

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

Confidence
91% confidence
Finding

This markdown file presents the skill name, description, and usage instructions only in Chinese. Under the policy rule for natural-language violations, forcing a specific language without user choice can be a locale/language policy issue when no opt-in or alternative is provided.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The title and function docstring are written only in Chinese, which imposes a specific language on users or maintainers without offering a language choice or explaining that the skill is region-specific. This matches the locale-policy category because the file's natural-language content is constrained to a single language with no opt-in.
