Morning Wakeup

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it claims: fetches weather and uses Sonos locally for a morning wake-up routine.

Install only if you are comfortable with the skill sending your configured location or coordinates to Open-Meteo and controlling the named Sonos speaker. Review any cron schedule you add, since recurring playback can be disruptive if configured incorrectly.

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

High
Category
MCP Tool Poisoning
Confidence
94% confidence
Finding

The stated purpose sounds like a simple morning automation, but the documented behavior includes external network lookups and local speaker control that are not transparently declared as permissions. This mismatch can mislead users about the operational scope of the skill and make risky side effects easier to hide inside an apparently harmless routine.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
92% confidence
Finding

The skill documentation describes behavior that requires network access to fetch weather and likely local command execution to control Sonos, but it declares no explicit tool scope or permissions. This creates a trust and review gap: users or orchestration systems may authorize or run a skill with capabilities that are broader than what its manifest transparently states.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% 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
Category
Not specified by scanner
Confidence
94% confidence
Finding

The geocoding URL hard-codes language=en, which forces English localization regardless of the user's preferences or locale. This is a natural-language policy concern because the skill does not offer a language choice or document a justified locale restriction.
