Security checks for vulnerabilities and agentic risk

Overview

This skill is a product-review writing workflow with disclosed web, screenshot, and optional Feishu document use, and I found no hidden execution, persistence, or data-stealing behavior.

Before installing, expect the skill to browse product websites, search public sources, inspect screenshots, and produce Chinese reports by default. Only ask it to create a Feishu document when you are comfortable sharing the report through that integration.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Finding

The instruction explicitly says to write the report in Chinese unless the user requests another language. This sets a forced default language without prior user opt-in, which is a natural-language locale policy concern under the stated rule.

Natural-Language Policy Violations

Finding

These lines require writing in Chinese by default and specify output length in Chinese characters. That enforces a locale/language default rather than offering the user an explicit language choice first.
