Fliggy

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Fliggy travel-booking guidance skill with no executable code, persistence, credential handling, or hidden authority.

Reasonable to install as a travel-advice aid. Verify live prices, refund terms, visa rules, and booking policies from current official or merchant pages before purchasing, and avoid sharing payment credentials or sensitive account details unnecessarily.

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

Finding

The manifest description includes both Chinese and English phrasing, while the rest of the skill is primarily Chinese. This can create an implicit language expectation without explicitly offering the user a language or locale choice, which may conflict with language/locale policy requirements.
