Security audit

Travel China

Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only travel planning skill with no evidence of hidden execution, persistence, data exfiltration, or destructive behavior.

Reasonable to install for travel planning assistance. Users should still confirm current visa, entry, flight, hotel, cancellation, and pricing details with official providers before making bookings or sharing document information.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill description is broad enough to trigger on a wide range of generic travel-planning and management requests, which can cause over-invocation and unintended delegation. In an agent system, this increases the chance the skill is selected outside its narrowly intended scope, exposing users to incorrect actions, unnecessary data sharing, or unsafe downstream booking/document workflows.

Vague Triggers

Category

Confidence
90% confidence
Finding

The usage examples are phrased as broad natural-language requests without qualifiers, so they reinforce permissive matching for many travel-related prompts. This can bias routing toward this skill even when the user only needs general advice, making accidental activation and inappropriate handling more likely.

Finding

This markdown skill file presents all guidance in Chinese and does not indicate that the user can choose another language or that the skill is intentionally limited to a Chinese-speaking audience. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy concern.
