Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Chinese-language daily news helper that fetches news from a disclosed third-party API without hidden local access or persistence.

Install only if you are comfortable using a Chinese-language news tool that contacts api.cjiot.cc when invoked. Consider narrowing activation phrases or confirming before calls when a message only loosely mentions news.

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

Natural-Language Policy Violations

Medium
Confidence
87% confidence
Finding
L003 的描述全文以中文定义技能用途，且文档中的回复模板、触发示例与交互方式均默认中文，没有说明是否支持其他语言或允许用户选择输出语言。根据规则，若技能对语言/locale 作出强制性默认而无用户选择或明确地域限定，属于自然语言策略问题。

Vague Triggers

Medium
Confidence
95% confidence
Finding
The trigger conditions include extremely broad keywords such as '新闻', '日报', and '头条', which can cause the skill to activate during ordinary conversation unrelated to the user's actual intent. Over-broad activation increases the chance of unintended external API calls and context capture, especially because the skill is designed to fetch remote content automatically.

Natural-Language Policy Violations

Medium
Confidence
97% confidence
Finding
This code includes natural-language documentation and console output in Chinese only, with no option for users to select another language or indication that the skill is intentionally limited to a Chinese-speaking audience. That creates a locale/language policy concern because the skill imposes a specific language without user opt-in.

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The file’s natural-language interface is written entirely in Chinese, including the primary description and usage example, which effectively imposes a specific language on users. There is no indication that this skill is region-specific or that users can opt into another language, which matches the language/locale policy violation criteria.
