youtube-downloader — agentic threat model

9.2AIVSS 9.2 · Critical

The overall risk posture is high due to the agent's capability to execute external CLI binaries (yt-dlp, ffmpeg) and write files directly to the host system, creating a significant attack surface for command injection and host compromise if input URLs or auth headers are manipulated.

OWASP AIVSS score rationale

AIVSS = (CVSS_Base + AARS) × Mitigation_Factor, where AARS = (10 − CVSS_Base) × (Factor_Sum / 10) × ThM

MAESTRO 7-layer threat model

Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.

L1 · Foundation Models⚠ not certain from listing

Not certain from the listing — The listing does not specify which foundation model orchestrates this skill. Standard LLM risks like prompt injection could be used to manipulate CLI arguments.

L2 · Data Operations⚠ not certain from listing

Not certain from the listing — No vector store or RAG is mentioned. The primary data operations involve downloading and writing media files to the host, risking path traversal or disk exhaustion.

L3 · Agent Frameworks✓ mapped

The agent orchestrates a pipeline using yt-dlp and ffmpeg. Insecure tool integration is a major threat, as malicious URLs or crafted auth headers could lead to command injection.

L4 · Deployment & Infrastructure✓ mapped

The agent invokes external CLI binaries and writes media files directly on the host. Without strict containerization or sandboxing, this poses a severe risk of host compromise.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — There is no mention of logging, guardrails, or monitoring for malicious inputs (e.g., sanitizing URLs before passing them to yt-dlp).

L6 · Security & Compliance (cross-cutting)✓ mapped

The agent handles authenticated streams using auth headers. If these credentials/headers are not securely stored or masked, they could be leaked in logs or exfiltrated.

L7 · Agent Ecosystem⚠ not certain from listing

Not certain from the listing — The agent is described as a standalone community skill; multi-agent interactions or marketplace trust boundaries are not defined.
