Freebeat Music Video Generator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a clear workflow guide for Freebeat media generation, with expected uploads and polling but no hidden code, persistence, or deceptive behavior.

Before installing, be aware that using the workflow may send audio files, image files, prompts, and media URLs to the Freebeat MCP service for processing. Avoid submitting sensitive, private, or copyrighted media unless you are comfortable with that service's terms and data handling.

A.I.G

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence

Finding

The skill description uses very broad activation cues, including generic references to Freebeat MCP and multiple tool names, which can cause the agent to invoke this skill in situations where the user did not clearly intend media upload or generation actions. In a skill that can upload files, import remote URLs, and start asynchronous generation jobs, unintended invocation increases the chance of unnecessary data disclosure, unexpected third-party processing, or accidental task execution.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill instructs the agent to upload local audio or images or import media from URLs, but it provides no warning that these actions transmit user data to an external service. This is risky because users may not realize that local files, media content, and remote resource URLs are being shared with a third party for processing, which can expose sensitive or copyrighted content.
