Travel China

Security checks for vulnerabilities and agentic risk

Overview

This is a travel-planning reference skill with no executable code or hidden behavior, though users should verify travel-document advice and share personal details carefully.

Before installing, consider that this skill may be invoked for broad travel-planning requests and includes some Chinese-language references. Treat visa, entry, health, and document guidance as a checklist only, and verify current requirements with official sources before booking or traveling.

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

Vague Triggers

Finding

The skill description is broad enough to match many generic travel-planning requests, which can cause the agent to invoke this skill in situations beyond the author's intended scope. Over-broad routing increases the chance that unrelated or more sensitive user tasks are handled by this skill, potentially exposing user data to unnecessary processing or causing unsafe delegation decisions.

Finding

The entire skill is written in Chinese and presents its guidance only in that language, with no indication that users may choose another language or that the skill is intended exclusively for a Chinese-language audience. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy concern.

Finding

This markdown file presents all guidance exclusively in Chinese, which can amount to a language-policy issue when the skill does not offer an opt-in choice or explain that it is intentionally region- or language-specific. The file contains no indication that Chinese is optional or required for a justified locale-specific use case.
