Meituan

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small Meituan public-page helper with disclosed limits and no bundled code, persistence, or credential handling.

Install only if you want an agent to help summarize or compare public Meituan listings and offers. Use it with explicit Meituan tasks, confirm any location-sensitive results, and avoid using it for login-only data, ordering, scraping at scale, or bypassing platform controls.

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 trigger description is broad enough to match many ordinary requests involving Meituan access or automation, which can cause the skill to activate when the user did not explicitly intend it. Overbroad activation increases the chance of unintended browsing, data extraction, or policy-sensitive automation on a third-party site, even though the skill text itself limits scope to public pages and discourages bulk scraping.
