Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Chinese A-share stock movement analysis skill that uses public market-data APIs and does not show hidden execution, persistence, or private data access.

Before installing, expect this skill to call the Today Investment finance-data dependency for public A-share quotes, news, announcements, and research sentiment. Its trigger phrases may activate during casual Chinese market questions, and its outputs are analytical only, not investment advice.

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

Vague Triggers

Medium
Category

Confidence
94% confidence
Finding

The trigger phrases are broad everyday market-chat terms like '为什么涨/为什么跌/拉升/跳水', which can cause the skill to activate when a user is merely discussing markets rather than explicitly requesting this workflow. Unintended invocation can lead to unnecessary tool use, surprise data retrieval, and the model responding in a specialized analysis mode the user did not intend.

Natural-Language Policy Violations

Confidence

Finding

The title and the full user-facing instructions are presented only in Chinese, with no indication that the user can choose another language. Under the policy, forcing a specific language without opt-in can be a natural-language policy violation unless the locale restriction is clearly documented and justified.
