Security checks for vulnerabilities and agentic risk

Overview

This skill is a local financial-ledger checker that reads user-supplied input and runs bundled Node.js code without network use or persistence.

Install only if you are comfortable using a Chinese-language local Node.js ledger checker. It does not appear to send data out or persist changes, but its conclusions are arithmetic/data-quality checks only and should not be treated as legal, audit, tax, or securities-compliance 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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • 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

整体上代码的主用途与描述高度相关,都是对关联方往来台账做本地化、无网络的免费版核对;不存在越权访问或无关能力。但描述有两点不准确:其一,‘每条结论引用原文’属于输出行为承诺,代码并未保留或摘录原文片段,只是生成字段化证据与数值重算结果;其二,描述列举的检查范围偏窄,而代码实际多做了负数余额、符号反转、计息情况缺失等检查,属于未充分声明的能力。基于题目要求,存在描述与行为的不一致,应判定为 mismatch。

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The file’s user-facing comments and guidance are entirely in Chinese, including the required input format and operational disclaimers. Under the policy, forcing a specific language without user opt-in is a natural-language locale violation unless the constraint is explicitly documented and justified.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The only natural-language content in this file is a Chinese table template, which indicates the skill output/content is fixed to Chinese. There is no accompanying opt-in, alternative locale, or justification that this skill is specifically region- or language-bound, which can violate language/locale policy requirements.

Intent-Code Divergence

Category

Confidence
85% confidence
Finding

The docstring says non-JSON input is treated as plain-text material such as '直接粘贴的合同全文', which contradicts the rest of the script and manifest that expect a related-party ledger with headers. The actual usage/help text consistently requires a ledger/table input, so this inline documentation is misleading about accepted material type and skill intent.
