Security checks for vulnerabilities and agentic risk

Overview

This skill appears to be a local invoice consistency checker with no hidden network, persistence, credential, or destructive behavior found.

Install only if you are comfortable running a local Node-based checker over invoice text. It does not verify invoice authenticity or tax compliance, and the bundled sample is Chinese-oriented, but the reviewed artifacts do not show data exfiltration, credential use, persistence, or destructive actions.

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

Low
Confidence
95% confidence
Finding
At L0087, the code hardcodes `toLocaleString('en-US', ...)`, which forces U.S. number formatting regardless of the user's language or locale. This is a natural-language policy concern because the file otherwise claims support for both Chinese and English invoices, but does not offer locale choice or explain why U.S. formatting is mandated.

Natural-Language Policy Violations

Low
Confidence
87% confidence
Finding
This JSON template contains only Chinese-language document content and does not indicate that the locale is optional or limited to a justified region-specific use case. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation.
