Security audit

Cn Split Lines

Security checks for vulnerabilities and agentic risk

Overview

This is a simple local text-splitting skill with no evidence of hidden access, persistence, credential use, or unsafe execution.

Review the documentation mismatch before relying on it: use --text and --separator with the current script, not the documented --file or --delimiter examples. The skill appears safe to install from a security perspective, but users who need English documentation or file-input support may find it incomplete.

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
88% confidence
Finding

The natural-language content that explains the skill and its usage is presented exclusively in Chinese, which can impose a language constraint on users without any opt-in or stated regional justification. Under the policy, forcing a specific language without user choice is a natural-language policy violation.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

This Python file contains user-facing natural-language strings only in Chinese, including the module docstring and CLI argument descriptions. That imposes a specific language on users without any visible opt-in, alternative locale, or documented region-specific justification, which matches the language policy violation criteria.
