Security checks for vulnerabilities and agentic risk

Overview

This skill appears to be a disclosed remote MCP for searching cruise products, with no local code, persistence, or hidden instructions in the inspected artifacts.

Before installing, users should understand that this is a hosted cruise-product MCP and their cruise-search queries may be sent to the listed remote service. Non-Chinese-speaking users may need translation because the package description and README are Chinese-only.

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
Category
Not specified by scanner
Confidence
86% confidence
Finding

The manifest description is written entirely in Chinese and presents the skill in that language without indicating that users can choose another language or that the skill is intended only for a Chinese-speaking or region-specific audience. This can violate language/locale policy when the skill effectively defaults to a specific language without user opt-in.

Finding

The README presents the skill description exclusively in Chinese, which can impose a specific language on users without offering an alternative or explicit opt-in. This matches the policy category for language or locale constraints expressed in natural language.
