墨迹天气 (Moji Weather CN)

Security checks for vulnerabilities and agentic risk

Overview

This is a simple China-focused weather lookup skill that openly redirects weather queries to domestic web sources and does not add code, persistence, credential access, or hidden behavior.

Install this if you want Chinese city weather queries to use Moji Weather or MSN China Weather instead of default international sources. Users who need foreign-city forecasts, official meteorological agencies, or Open-Meteo/wttr.in specifically should avoid or disable this skill for those requests.

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

Finding

The description states the skill overrides the built-in weather skill and '强制使用国内数据源', which imposes a locale-specific behavior by default. The file does not offer user opt-in, language choice, or a clearly bounded compliance-only justification; instead it broadly applies to weather requests in China-related contexts.
