旅行插头电压查询

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local Chinese-language travel plug and voltage lookup tool with no evidence of network access, persistence, destructive behavior, or data exfiltration.

Install this if you want Chinese-language, offline travel plug and voltage guidance. Be aware that it relies on embedded reference data, so verify critical electrical compatibility against device labels or hotel/local guidance before using high-power appliances; the unused PROXY_TOKEN read is unnecessary but showed no data flow or security impact in the inspected code.

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

Findings (3)

Lp3

Medium

Category: MCP Least Privilege
Confidence: 70% confidence
Finding: Without declared permissions the skill's intent is opaque and cannot be validated.

Natural-Language Policy Violations

Medium

Confidence: 94% confidence
Finding: The skill description and all user-facing output strings are presented in Chinese, which effectively forces a specific language for users. The file does not indicate that Chinese is optional, user-selected, or justified as a region-specific constraint.

Natural-Language Policy Violations

Medium

Confidence: 91% confidence
Finding: Multiple returned messages, errors, and guidance strings are hardcoded in Chinese across the executable functions. Because the skill provides no mechanism for language selection or explicit regional scoping, this violates the language/locale choice policy.
