Cruise Product Skill Pack

Security checks for vulnerabilities and agentic risk

Overview

This appears to be a benign cruise-search skill, with the main caveat that it sends user queries to an external MCP gateway and the documentation is partly boilerplate and mixed-language.

Before installing, confirm you are comfortable using a remote cruise-search MCP service and sending cruise search inputs to the listed gateway. The skill does not show local system access or persistence risks, but its documentation should be read carefully because some sections are generic or mixed-language.

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

Findings (2)

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 98% confidence
Finding: The file mixes English introductory text with Chinese-only publisher and installation guidance, which imposes a specific language on users without opt-in. This is a natural-language policy issue because essential usage instructions are not consistently available in a user-selectable language.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The file presents core usage and capability sections in Chinese, while the surrounding metadata and title are in English. This effectively imposes a language preference on users without opt-in or justification, which matches the language/locale policy concern for natural-language content.
