Security audit

Waimai Decision Assistant

Security checks for vulnerabilities and agentic risk

Overview

This skill gives public takeout-ordering advice and explicitly avoids login, payment, order submission, cookie handling, and persistence.

Installers should treat this as an advisory takeout comparison skill. Do not rely on it to place orders or access accounts, and recheck final prices, fees, delivery time, coupons, and terms before paying.

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
Vulnerability Patterns

Vague Triggers

Confidence

Finding

The phrase 'Use this skill when the user wants public buying, ordering, sourcing, or booking guidance' is very broad and extends well beyond takeout decisions. Because it lacks concrete trigger boundaries or exclusion examples, it could cause this skill to be invoked for generic shopping or booking requests not actually in scope.

Natural-Language Policy Violations

Confidence
79% confidence
Finding

The skill description uses untranslated Chinese terms like '起送价, 配送费, 满减' without indicating language choice or offering an alternative locale. This can impose a language/locale assumption on users rather than explicitly allowing them to choose their preferred language.
