guizang-social-card-skill — agentic threat model

4.8AIVSS 4.8 · Medium

This agent is a specialized design-generation skill with low agentic risk, acting primarily as a deterministic asset generator with minimal autonomy or external tool access.

OWASP AIVSS score rationale

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

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.

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✓ mapped

Utilizes Claude Code / Codex foundation models. Primary threats include prompt injection designed to bypass template constraints or generate inappropriate/copyright-infringing visual layouts.

L2 · Data Operations⚠ not certain from listing

Not certain from the listing — processes user-provided articles, scripts, screenshots, and videos. Risks include processing malicious input files (e.g., polyglot files or exploit payloads disguised as media) and potential data leakage of sensitive input drafts.

L3 · Agent Frameworks✓ mapped

Operates as a skill within Claude Code. Vulnerabilities are limited to how the framework orchestrates the template rendering and whether input parameters can trigger command injection during image/video processing.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — depends entirely on the host environment running Claude Code. If executed locally or in an unsandboxed container, malicious inputs exploiting image rendering libraries could lead to local code execution.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — likely lacks dedicated guardrails or observability for generated content, relying instead on the parent framework's safety filters to block harmful outputs.

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

As an open-source skill, it lacks built-in enterprise compliance, access controls, or audit logging, shifting all security and licensing compliance responsibilities to the end-user.

L7 · Agent Ecosystem✓ mapped

Designed as a self-contained skill with bundled templates. It has no native multi-agent coordination or marketplace interactions, minimizing ecosystem-level cascading risks.
