Security checks for vulnerabilities and agentic risk

Overview

This skill is a local R&D expense table checker with no evidence of network use, persistence, credential handling, or hidden behavior.

Before installing, understand that this is a Chinese-language, local-only checker for copied R&D expense collection table text. It can help find arithmetic and table consistency issues, but it explicitly does not provide tax advice or check all paid-version items.

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 docstring says non-JSON input is treated as plain-text material such as a pasted '合同全文', which implies broader document types are acceptable. However, the manifest and the rest of this runner consistently describe the skill as checking R&D expense collection tables with headers, and insufficient-input messaging also requires that specific table format.

Natural-Language Policy Violations

Low
Category

Confidence
95% confidence
Finding

The only natural-language content in this manifest-like JSON file is entirely in Chinese, which indicates a fixed language/locale expectation with no opt-in or alternative. Under the policy rule for language or locale constraints, this is a potential violation because the file does not offer the user any language choice or explain why Chinese is required.
