Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent study-material generator with no bundled executable code, persistence, credential handling, or hidden destructive behavior.

Installers should expect this skill to create learning-material files from provided study content and possibly use search if the user chooses that path. Review generated study content for accuracy, especially when no source material is uploaded.

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

Vague Triggers

Finding

The trigger list includes broad everyday phrases such as “学习材料”, “笔记生成”, “测验”, and “课件”, which are likely to overlap with ordinary user conversations and can cause unintended skill activation. This increases the chance that the skill takes over contexts the user did not explicitly intend, potentially redirecting workflows, generating files unnecessarily, or altering expected assistant behavior.
