Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed remote MCP integration for retrieving cruise product information, with no local code or hidden high-impact behavior found.

Before installing, confirm you are comfortable using a remote MCP service at the disclosed olavacations.com endpoint and that Chinese-language documentation is sufficient for you. The reviewed artifacts do not show local execution, credential handling, persistence, or destructive behavior.

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
94% confidence
Finding

The natural-language description at L03 and L12 is Chinese-only, and the file does not indicate that the skill is region-specific or provide any user opt-in for language/locale. This can violate language/locale policy because it implicitly forces a specific language for users regardless of preference.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The manifest description is written entirely in Chinese and implies the skill is intended to operate in that language, but it does not state that this is an optional locale choice or a region-specific requirement. Under the language/locale policy, a skill should not implicitly force a specific language without user opt-in or clear justification.

Natural-Language Policy Violations

Low
Category

Confidence
90% confidence
Finding

The skill description is presented only in Chinese, which can constitute a language/locale policy issue when no user opt-in or alternative language is offered. The stated policy specifically flags forced language choices in natural-language content across all file types.
