Music

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple local music-journaling helper that stores user-provided music notes in markdown files under a disclosed music folder.

Before installing, be aware that the skill may create and maintain a ~/music/ folder containing personal music preferences, concerts, collection notes, and memories. This is expected behavior for the skill, but users who prefer another location should direct the agent to use a different folder.

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

Missing User Warnings

Low

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The skill directs creation of ~/music/ in the user's home directory without an explicit user-facing warning or confirmation step. While this is not inherently malicious, writing to the home directory can unexpectedly modify a user's filesystem and may create privacy or clutter concerns if done automatically.
Content: No source excerpt is available for this finding.
