Weather

Security checks for vulnerabilities and agentic risk

Overview

The scanners classify this weather skill as benign, with the main caveat that its weather lookup may send your location to an external service without a privacy warning.

Before installing, consider whether you are comfortable sharing the location you request with wttr.in. Prefer city-level locations if that is enough for your forecast.

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

Findings (1)

Weather lookup instructions omit a privacy warning about sending the user's requested location to a third-party service.

Medium

Category: Output Handling
Confidence: 94% confidence
Finding: The workflow instructs the agent to request weather from wttr.in using a location, which line 26 allows to be precise coordinates. Although the service URL is shown, the skill does not warn users that their location will be transmitted to an external provider; the external-content warning addresses response safety rather than location privacy.
