Security audit

Media Cli

Security checks for vulnerabilities and agentic risk

Overview

This skill is purpose-aligned for managing a media stack, but it asks users to install unaudited, mutable external code that can control media services and use stored API keys or SSH access.

Review the external GitHub repository before installing, prefer a pinned commit or signed release, and only configure API keys and SSH access for services you are comfortable letting an agent manage. Be especially careful with download removal, file deletion, and bulk pause or refresh commands.

A.I.G

Vulnerability Patterns
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • 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
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Sudo/Root Execution

Finding

Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

The setup wizard asks for API URLs and keys, saves to `~/.config/media-cli/config` (chmod 600).

Confidence
91% confidence
Finding

The skill exposes destructive commands such as removing media, pausing/resuming all downloads, and deleting download data, but does not prominently warn users or agents about their side effects. In an AI-agent context, concise command examples can be executed automatically or suggested without sufficient confirmation, increasing the risk of accidental library changes or data loss.
