Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Chinese document-analysis helper that reads user-provided documents or URLs and writes derived reports without bundled code or persistence.

Install this if you want a Chinese-language document summarization and comparison workflow. Be mindful when using it on private documents or login-protected webpages, since it may read that content through file, web, OCR, or browser tools and create reports in an output directory.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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
83% confidence
Finding

All user-facing instructions, triggers, examples, and output guidance are presented only in Chinese, which effectively imposes a language choice on users. The file does not state that the skill is region-specific or provide an opt-in or alternative language path, so this appears to violate the language/locale policy criterion.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The auto-load trigger phrases are broad enough to match common, everyday requests such as '帮我看看', '分析', or '整理成文档', which can cause the skill to activate outside a clearly document-processing-specific context. This increases the chance of unintended tool use, unnecessary file or web access, and scope expansion without the user explicitly selecting this capability.
