Security checks for vulnerabilities and agentic risk

Overview

The skill’s cloud uploads, paid video generation, and optional project edits are disclosed and fit its music-visualization purpose.

Use this skill if you are comfortable uploading selected media to Gitruck Cloud and paying duration-based charges. Protect your API key, review the CLI version you install, and keep a backup before editing an existing project.

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

Description-Behavior Mismatch

High

Category: MCP Tool Poisoning
Confidence: 96% confidence
Finding: The supplied commands perform timeline editing on an existing clip. They neither invoke music-visualizer nor show an audio-to-spectrum-video workflow. Although clip editing could support video production, this chunk provides no connection to visualization generation, making its demonstrated purpose materially different from the declared purpose.
