Security checks for vulnerabilities and agentic risk

Overview

This skill is a local overdue-interest worksheet checker with narrow, disclosed behavior and no evidence of hidden network, persistence, credential, or destructive activity.

Install only if you are comfortable using a Chinese-language local checker for overdue-interest worksheets. Treat its output as arithmetic/table review, not legal advice, and note that the free version explicitly omits several checks such as rate-cap and date-anomaly validation.

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

Natural-Language Policy Violations

Medium
Category

Confidence
96% confidence
Finding

The file’s natural-language description, user-facing advice, labels, and sample input are entirely in Chinese, which effectively constrains use to a specific language/locale. There is no indication that users can choose another language or that the locale restriction is explicitly documented as an intentional regional limitation.

Natural-Language Policy Violations

Confidence
90% confidence
Finding

The JSON sample text is entirely in Chinese and provides no indication that language selection is optional or limited to a justified region-specific use case. This can violate language or locale policy because it implicitly constrains the skill's output or input format to a specific language without user opt-in.

Finding

L075 的注释写明“不是 JSON 就当作纯文本材料(例如直接粘贴的合同全文)”,但本文件其余说明和 manifest 都反复限定输入应为逾期利息计算表且含表头。这里的文档示例会让人误解技能可对合同全文做核对,和代码宣称的专门用途存在意图层面的偏差。
