Security checks for vulnerabilities and agentic risk

Overview

This skill is a Chinese-language market and news summary helper that uses public news and market-data sources without hidden persistence, credential access, or destructive behavior.

Install this only if you want a Chinese-language report generator that performs live public web, RSS, and market-data lookups. Verify important financial or geopolitical claims independently, because the package includes broad reporting instructions but only a narrow market-data helper script.

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

MCP Tool Poisoning
Confidence
94% confidence
Finding
The documented behavior promises broad intelligence aggregation, alerting, correlation, and analysis, but the implementation apparently only performs narrower market-data fetching. This mismatch is dangerous because users and orchestrators may grant trust, permissions, or make decisions based on capabilities the skill claims to have but does not actually implement or validate, creating deceptive operational assumptions.

Medium
Category
MCP Least Privilege
Confidence
89% confidence
Finding
The skill instructs the agent to perform broad network access such as fetching RSS feeds, market data, and live news, but it does not declare any explicit tool scope or allowed-tools boundary. This weakens least-privilege controls and can let the skill operate with whatever network capabilities the host agent happens to have, increasing the chance of overbroad data access or unintended outbound requests.

Natural-Language Policy Violations

Medium
Confidence
93% confidence
Finding
The skill description and all operational instructions are written as mandatory Chinese-language guidance for generating reports, with no indication that users may choose another language or locale. This is a natural-language policy concern because the skill appears to enforce a specific language by default rather than offering user choice or documenting a justified region-specific constraint.

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The config sets the output language to "zh-CN" unconditionally. This is a natural-language locale constraint, and the file does not indicate any user opt-in, language selection mechanism, or region-specific justification for requiring Chinese output.

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The module title and description are written entirely in Chinese, and the user-facing status message is also hard-coded in Chinese. This imposes a specific language/locale without offering opt-in or documenting a justified region-specific requirement, which matches the policy violation criteria.

Confidence

Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Natural-Language Policy Violations

Low
Confidence
94% confidence
Finding
This markdown file is natural-language output content, and it appears to require Chinese for all headings and bullets. Under the language/locale policy rule, forcing a specific language without user opt-in can be a policy violation when no justification or choice is provided.

Natural-Language Policy Violations

Low
Confidence
83% confidence
Finding
The package description is written entirely in Chinese and presents the skill as a general-purpose global intelligence summary tool, with no indication that the language restriction is optional or region-specific. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation.
