Security checks for vulnerabilities and agentic risk

Overview

This is a local prepaid-card reconciliation checker, and the inspected code matches that purpose without hidden network, credential, persistence, or destructive behavior.

Install only if you are comfortable running a local Chinese-language Node.js checker on prepaid-card reconciliation data. It is a disclosed free subset and should not be treated as full accounting, tax, or legal advice.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • 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

Finding

The file’s docstrings, guidance text, error messages, findings, and disclaimer are written entirely in Chinese, including all user-facing strings returned by run(). There is no opt-in, locale selection, or documentation that this skill is intentionally restricted to a Chinese-speaking or region-specific audience.

Finding

The inline comment says non-JSON input is treated as plain-text material such as '直接粘贴的合同全文', which contradicts the skill's stated purpose and the rest of the file that expects a prepaid-card reconciliation table with headers. This is not just incomplete documentation; it names a different document type and can misstate developer intent about what inputs the tool is meant to handle.
