04 Supply Chain

Security checks for vulnerabilities and agentic risk

Overview

This is a Chinese-language supply-chain guide with local calculator examples and no evidence of hidden system access or data export.

Install only if a Chinese-language community group-buying procurement reference is useful to you. Treat the included calculators as advisory examples and verify formulas, supplier ratings, legal claims, blacklist decisions, and reporting actions with qualified business or legal review before relying on them operationally.

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 skill description and all operational guidance are written entirely in Chinese, and the embedded tool prompts and outputs also require Chinese interaction. There is no indication that users may choose another language or that the Chinese-only constraint is a documented, justified regional limitation.

在该技能的采购语境中,账期通常表示供应商给予平台的付款延期,账期越长通常越有利于采购方;但 L0725-L0728 将 payment_days 直接作为“资金占用成本”增加项,导致账期越长总采购成本越高。结合前文大量将更长账期视为议价优势的说明,这里代码对“账期”的经济含义实现与注释/技能文档意图相反。

Finding

L0398-L0400 的模块文档明确写明输出包含“历史评分追踪”,且数据类在 L0440-L0441 定义了 history 字段。但后续计算、序列化和交互流程中均未读取、更新或持久化该字段,实际行为只进行单次评分输出,和文档描述直接不符。
