Security audit

WeChat Games Reporter

Security checks for vulnerabilities and agentic risk

Overview

This is a small reporting skill that clearly describes scraping public WeChat mini game rankings and delivering the generated report through Feishu.

Before installing, make sure you are comfortable with the skill sending generated reports through Feishu and verify the intended recipient, especially if you add private business commentary or non-public analysis to the report.

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

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill explicitly states it will create a Feishu document and send it via direct message, but it does not warn the user that generated content will be transmitted to an external messaging platform. This can lead to unintentional disclosure of scraped data, analysis outputs, or sensitive business context if users invoke the skill without realizing it performs outbound delivery.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
79% confidence
Finding

The skill is centered on WeChat mini games, 应用宝, and Feishu, indicating a specific regional/language context, but the description does not explicitly state that the skill is intended for a China-specific market or offer any user choice around locale. Under the policy, forcing a specific language or locale without opt-in or clear justification can be a natural-language policy issue.
