Security checks for vulnerabilities and agentic risk

Overview

This is a simple educational explanation skill with no code execution, data access, persistence, or hidden privileged behavior.

Installers should expect this skill to steer explanation requests into a detailed, structured teaching format, likely in Chinese unless the agent follows the user's language. Consider narrowing triggers if you want to avoid frequent activation on ordinary explanation requests.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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
Not specified by scanner
Confidence
87% confidence
Finding

The skill metadata and content are written to produce Chinese-language output by default without explicitly offering user choice of language. This can lead to mismatched responses, reduced usability, and possible misunderstanding when an English or other-language user triggers the skill.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The trigger list contains broad English terms like "teach" and "knowledge" plus generic Chinese phrases such as "讲解" and "解释", which can match many normal user requests unrelated to this specific skill. This can cause unintended activation, routing users into the skill unexpectedly and overriding more appropriate instructions or workflows.
