Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only UI design skill for M5Stack UIFlow2 screens, with no hidden execution, persistence, credential handling, or destructive behavior found.

Install this skill if you want Chinese-language UIFlow2 design guidance for M5Stack devices. Non-Chinese users may need to ask the agent to respond in another language, and generated code should still be checked against official UIFlow2/M5Stack documentation and tested on the target device before deployment.

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

Medium

Not specified by scanner
Confidence
95% confidence
Finding

The instruction '默认用中文说明,代码和 API 名保持英文' sets a default response language policy in natural language. This is a locale/language constraint that is not presented as user choice or clearly justified as a region-specific requirement, which can violate the language/locale policy rule.

Confidence

Finding

The file content is written entirely in Chinese and line L003 states the guidance directly in Chinese without offering an alternative language or indicating that the skill is intentionally limited to a Chinese-speaking audience. Under the policy, forcing a specific language without user choice or clear regional justification is a natural-language policy violation.

Finding

Line L03 instructs that review results be organized in Chinese, and the entire checklist is written only in Chinese. This imposes a specific language/locale without any opt-in, alternative, or stated region-specific justification, which matches the language-policy violation criteria.

Finding

This markdown file presents all guidance in a single forced language, which can violate language/locale policy when users are not given an opt-in or alternative. The document does not indicate that it is intended only for a Chinese-speaking audience or provide any language selection mechanism.

Natural-Language Policy Violations

Confidence
95% confidence
Finding

Line L003 states the design system guidance entirely as a directive in Chinese, and the file consistently requires Chinese-language interaction patterns without any user opt-in or explanation that this skill is region-specific. This is a natural-language locale policy concern because it effectively forces a specific language context rather than offering language choice.
