Security checks for vulnerabilities and agentic risk

Overview

The skill’s lottery creation, account queries, and data exports are clearly disclosed and controlled by user authorization.

Review the OAuth permissions and final preview because creation produces a live activity. Exports may contain personal information, so protect their download links. Displayed times use Beijing time (UTC+8). The remote service’s implementation was not independently verified.

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

Displayed timestamps must be converted to Beijing time without offering a timezone choice.

Finding

The workflow explicitly requires converting timestamps to Beijing time whenever they are shown to the user. This imposes a locale-specific presentation without user opt-in or a documented regional requirement justifying the restriction.
