ZoneFoundry for Sonos

Security checks for vulnerabilities and agentic risk

Overview

This skill appears to be a clearly disclosed remote Sonos control integration, with the main user consideration being that it can affect speakers and reminders in the home.

Install this only if you want an agent to control your Sonos system through ZoneFoundry's cloud service. Treat the API key like a password, revoke it if no longer needed, and consider requiring confirmation for announcements, reminders, volume changes, grouping, or playback that could affect other people at home.

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 enables privacy-sensitive and real-world actions such as speaker announcements, reminders, and remote playback/control, but it does not prominently warn users that commands may cause audible actions in their home or expose household presence and activity patterns. In practice, an agent could trigger announcements or reminders without the user fully appreciating the privacy and nuisance implications, especially when operating away from home via a cloud relay.
