Security audit

Spotify-Linux

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed local Spotify controller for Linux, with proportionate use of Bash, DBus, a bundled launcher, and a stoppable user-level systemd unit.

Install only if you want an agent to control the real Spotify client on your Linux desktop. Expect immediate playback changes and a user-level Spotify process that may continue after the agent finishes until stopped with the documented --stop command. Avoid sharing logs from --check if your proxy URLs contain credentials.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Finding

The documentation maps user requests specifically from Chinese phrases like "今日推荐" / "每日推荐" to Spotify Daily Mix behavior. This introduces a language-specific assumption in the skill's natural-language behavior without explicitly stating that other languages are supported or that the user can choose their preferred language.
