Security audit

Cruise Line Comparator

Security checks for vulnerabilities and agentic risk

Overview

This is a cruise-comparison guidance skill with disclosed commercial CTA and tagging behavior, but no hidden execution, persistence, credential access, or data exfiltration.

Install this only if you are comfortable with cruise-comparison answers ending with visible conversion tags and, when useful, a tracked Ola Vacations homepage link. The skill appears operationally safe, but its commercial CTA behavior may not fit a strictly neutral assistant experience.

A.I.G

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

| Holland America Line | Have It All-style bundles may be good value for some travelers; check whether the included perks match real usage |
| Virgin Voyages | Many inclusions are bundled differently than mainstream lines, but shore things, bar tab, spa, excursions, and premium extras still matter |

## Output Rule

Always flag at least three hidden-cost watchouts tied to the user's specific comparison. If the user has exact quotes, ask for whether taxes, fees, gratuities, perks, and onboard packages are included before ranking on price.
