Weather Tools

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple weather helper that shows curl commands to wttr.in, with no hidden code, persistence, or credential access.

Install only if you are comfortable sending weather queries, location names, IP/request metadata, and format parameters to wttr.in. Avoid using sensitive private location labels in queries.

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 skill repeatedly instructs users to run curl against wttr.in, which sends network requests and potentially location queries to an external third-party service, but it does not clearly disclose that data leaves the local environment. While this is normal for a weather skill and there is no obvious attempt to exfiltrate sensitive data, the lack of a user-facing warning can still cause unintended privacy or policy issues in restricted environments.
