Cn Sort Lines

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small local text-line sorting tool with Chinese-only documentation and no hidden system access.

Install this if you are comfortable with a Chinese-language command-line helper for sorting pasted text. The included promotional links are external website links, so review them separately before clicking, but the local script itself does not require network, credentials, or file access.

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

Natural-Language Policy Violations

Medium
Confidence
92% confidence
Finding
The natural-language content in the skill forces a specific language/locale for users, and there is no indication that Chinese is optional or that the skill is intentionally limited to a Chinese-only audience for a documented reason. This can violate language/locale policy requirements that require user choice or explicit justification.

Natural-Language Policy Violations

Low
Confidence
92% confidence
Finding
The file uses Chinese-only natural-language strings in the module docstring and CLI argument descriptions, which imposes a specific language on users. The policy allows locale constraints when they are explicitly justified or optional, but this file provides no opt-in or explanation that it is intended only for Chinese-speaking users.
