Meituan

Security checks for vulnerabilities and agentic risk

Overview

This is a Markdown-only Meituan decision guide that uses public or user-provided information and explicitly avoids account access, cart changes, checkout, or payment.

Use this skill as advice for visible Meituan offers only. Avoid sharing personal details in screenshots, and verify final payable amount, ETA, stock, coupon eligibility, refund terms, and payment details yourself in the app before ordering.

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

### 3. Compute Checkout Reality

Do not judge by headline discount alone.

Compare:
Confidence
85% confidence
Finding
Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

Natural-Language Policy Violations

Low
Confidence
89% confidence
Finding
This markdown file includes substantial user-facing release notes in Chinese alongside English, but it does not indicate whether the skill supports multiple languages or whether a specific locale is required. Under the policy rule, forcing or assuming a language without user opt-in can be a natural-language policy issue.
