Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple remote MCP integration for searching cruise products, with no local executable code or persistence, though users should know their queries go to an external gateway.

Before installing, confirm you are comfortable sending cruise search criteria to the listed CruiseSkillBridge/olavacations remote endpoint, and avoid including secrets, payment details, or sensitive personal information in search inputs.

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 (3)

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The skill documentation instructs users to send POST requests to an external endpoint and states that published calls will be routed through a gateway and counted in console statistics, but it does not clearly warn that request contents may be transmitted, logged, or retained by third-party infrastructure. This creates a real privacy and data-handling risk because users or agents may submit sensitive search criteria, personal data, or business data under the assumption they are talking only to the skill backend.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 92% confidence
Finding: The skill description is written only in Chinese and provides no indication that users may choose another language or that the skill is intentionally limited to a Chinese-speaking locale. Under the stated policy, forcing a specific language without user opt-in or clear justification is a natural-language policy concern.
