Ctrip

Security checks for vulnerabilities and agentic risk

Overview

This is a static travel-planning reference skill with no executable code, persistence, credential handling, or hidden behavior.

Before installing, understand that this skill provides general travel checklists and recommendations rather than verified live booking or visa advice; users should confirm current prices, policies, and document requirements with official sources or providers.

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

Finding

The skill description is broad enough to activate on many generic travel-planning requests, which can cause the agent to invoke this skill in situations where narrower or safer handling would be more appropriate. Overly broad routing increases the attack surface for prompt-injection or unsafe downstream behaviors in referenced content because the skill may be selected more often than intended.

Finding

The entire skill is written in Chinese and does not indicate that language selection is optional or limited to a justified Chinese-language context. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation.
