Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed remote MCP connector for comparing cruise products, with no bundled executable code or local persistence.

Before installing, confirm you are comfortable sending cruise-comparison requests to the disclosed remote MCP service at olavacations.com. Non-Chinese-speaking users may find the current description under-documented, but the inspected artifact does not show hidden local code, persistence, credential access, 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
93% confidence
Finding

The user-facing description is written entirely in Chinese, and the file provides no indication that language selection is optional or that the skill is intentionally limited to a Chinese-speaking region or audience. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation.

Natural-Language Policy Violations

Medium

Confidence
95% confidence
Finding

The natural-language description in both the manifest header and embedded server.json uses Chinese only, which can impose a language requirement on users without opt-in. The policy allows locale constraints only when they are explicitly documented and justified, or when users are given a choice.

Natural-Language Policy Violations

Confidence
91% confidence
Finding

The natural-language description is entirely in Chinese, with no indication that the skill is region-specific or that users can choose another language. This can violate language/locale policy because it imposes a specific language without opt-in or justification.
