Security audit

Cn Suffix Tool

Security checks for vulnerabilities and agentic risk

Overview

This is a small local text utility that adds a suffix to each input line and does not show security-impacting behavior.

Install only if Chinese-language documentation/help text is acceptable. The included script is simple and local, but review the promotional links separately before visiting them.

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
95% confidence
Finding

The natural-language description forces a specific language/locale for users by presenting the skill instructions only in Chinese. The policy for this category says to flag language or locale constraints when the skill does not offer a user choice or clearly justify the restriction.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
91% confidence
Finding

The file’s user-facing natural language strings, including the module docstring, argument parser description, and help text, are all in Chinese with no indication that the user can choose another language. This creates a locale/language policy concern because the skill implicitly enforces a specific language rather than offering opt-in or documenting a justified region-specific constraint.
